I'm assuming I may have inadvertently flipped a software switch somewhere along the way but I've just finished importing a few hundred images I've taken with EKOS (3.6.0 Stable running on MacOS 12.6 (Monterey)) and there is no filter record in the FITS header. 60+ other records but no filter information. This somewhat complicates pre-processing but thankfully there are workarounds short of editing the FITS header. This is happening for both Light and Flat frames. I've been using EKOS/KStars for over a year and haven't run into this before.
Is there something obvious I'm missing or is this occurring for others?
