NullPointerException in Batch Crop

Hello

I keep getting the following error when I batch crop images; typically they are normalized Broadband (OSC) and Narrowband (dual NB) Fit files. This started to occur at beta44 (wasn't a problem before) and it is still there in beta45. It occurs NOT during the crop but during the save... Here is the error in beta44:

---
Astro Pixel Processor - 2.0.0-beta44
Oracle JDK 26.0.1 - Windows-64-bit

Encountered error in module:
FileDetailListUpdater

Error message:
java.lang.NullPointerException: Cannot invoke "String.equals(Object)" because "this.a[<local25>]" is null

Cause:

Please note, however, that as far as I can tell, the crops appear to have been successful.

Here is the log portion (I added the "arrows"):
