Extracting narrowband data from multi narrowband filter shot on a OSC

Look video tutorial 

AstroStace ! The same for ''Dual band filters'' like Optolong L-enhance (or Astronomik UHC) or similar filters...

Hello there Brown Dwarf,

You are very smart young Lady & I like like your astro videos.

Sorry to bother you but request help if you would be so kind.  I just got a trial download of latest  APP ver 1.082. And trying to follow your procedure for Processing on L-Enhance subs. I have just ONE sub  captured with an ASI183MC w/ L-en filter via SharpCap Live Stack. Spitting into RGB channels works fine. But can't seem to extract HA or OIII from my L-Enhance Sub:

1. After split into R,G,B I exit APP to be safe & come back selecting Tab 0, checking Force Bayer/x-Trans CFA & selecting HA/OIII - Extract HA.

2. Load my original L-Enhance sub, don't do Registration ( I have only one sub ) & integrate but I end up always with an RGB image. ( eg - no file with HA-Extract.tiff suffix as shown in stojang's ( UK Astro girl ) U-Tube video on Altair TriBand Filter Processing which is linked on APP Forum with your Procedure.
