Missing filter tag in FITS header

I have this same problem using my RPi as a server at the mount. It saves the Filter keyword on the very first file captured after startup but then none afterwards. Been this way for a while. I am running Stellarmate OS on the RPi and  used Software Updater to update the OS yesterday before my run last night. Not having the Filter designation keyword in the Fits Header is inconvenient when using Weighted Batch Preprocessing Script 2 in PixInsight. All the frames (including Flats) have to be added using the Add Custom button which then requires filling out by hand information about the files. Also my Mac version (3.5.5) of KStars/Ekos does not record the Filter keyword in the Fits Header when capturing files - normally use this set up when recording Flats with my indoor panel. I am using the ZWO ASI6200 MM and EFW filter wheel.

In the ASI6200 tab in INDI Control Panel --> Options, what's "Filter" set to?

Jasem, when there is no Filter info in the Fits header, that field was empty. I discovered this today on my surrogate RPi (duplicated OS) inside (I bring in the telescope when not imaging at night and leave the operational RPi on the mount, so won't be able to test this on the real set up until the next observing session). Here is what I am seeing. When I connect the INDI server via Ekos, it connects immediately to the camera and EFW. The Capture window shows the camera and filter wheel.  I normally have a sequence of exposures with different filter wheel selections like LRGB, which I build manually using the filter drop down menu.  When the sequence is running, if I watch the ASI6200 tab/Options/Filter in the INDI Control Panel it sometimes just randomly goes blank and stays blank for the rest of the sequence, even if the filter changes. Otherwise the value in that field is "ASI EFW" as normal. So of course if the Snoop value is blank in the Options tab, I get no Fits header keyword for Filter. When this happens the FW drop down menu in the Capture window also goes blank, --.  This happens without any operator intervention. I will turn on verbose logging on my next night time run and keep an eye on the Snoop value and the FW drop down menu and try to send a log file. Thanks for your question.

Is it possible you're loading a sequence file that has a filter wheel as blank "--" ?? or this happens randomly? I just connected with ASI EFW + 178MC and tried to reproduce the behavior but couldn't.
