UPDATE FROM MABULA
I have had a very rough 2 months unfortunately health wise. I was struck 3x in a row with bacterial infections. The second infection occurred  after a routine hospital checkup and I became very sick. I had to rest and take a lot of antibiotics. Once I was recovering and restarting work 1 month ago, I again became sick. The infection was not yet gone, so even more antibiotics and rest was needed. Needless to say, it took a lot of my energy and I needed a lot of rest.
Finally, the infection is really gone and my energy is coming back step-by-step now and I have started work again. I am terribly sorry to have kept you waiting for support. I will address all outstanding questions and e-mails step-by step and will be on the forum daily from today.
APP 2.0.0-beta47 will come soon as well, a lot of work was already completed before I became very ill, so the release is also nearly ready for you. Beta47 will be much faster actually. Many workflows will be more than 2x faster, mosaics can even be 10x faster than before because registration really received a major boost... all compared to beta46. Â Before I release it, I will make sure that everything is working properly and then I will release it.
I am getting the error message listed in the subject line but my flats and dark flats (made in N.I.N.A.) are of the same gain and exposure time and I confirmed it in the fits image headers. So why am I getting this message?
Did you load the dark flats with the darkflat button, can you confirm all settings are indeed the same (including offset)?
Yes- dark flats loaded with dark flat button and offset the same. Â I can re-run it to see if it happens again but my camera settings have not changed for months and I have not had this issue in the past.
Interesting, yes please restart APP just to be sure and if it happens again I'll ask for your data to see if I can figure it out.
ps. are you using the latest APP version?
I just uploaded the latest APP version and re-ran my images. Interesting in that the error did not appear during calibration but I received a warning during star analysis that my images are underexposed or I have a light leak in my optical system. I am imaging a galaxy (M94) under my Bortle 7 sky (I usually only do narrowband) on a C11" EdgeHD @ f/10 with a ASI6200mm Pro (0.27 arcsec/pixel) with average/below average seeing. This usually leads to some oversampling but I never have trouble with NB imaging on this system.Â
As you can see in the attached luminance stacked and fully stretched image, it does not look good. I used a gain of 100 and offset of 50 with 120s exposures, which is pretty standard by those using this camera for LRGB. Any suggestions would be appreciated. Â

Great, so the error was fixed. This warning is just to inform you that you can get a better result when you expose for longer, 100 pixels clipping isn't terrible, so you can continue with that but I'd say to go for 180s instead. That may solve this issue as well and improve your data at the same time.
The gradient you have in the result is pretty strong, but you may be able to get that sorted with the LP- (Light Pollution) tool in the tools tab.
Thanks for the feedback and suggestion, Vincent.
