I just noticed an issue with taking flats after the last update I did. I select an exposure time of 1 second, ADU of 28000, 25 frames and start the process. It doesn’t have any problem adjusting the exposure time to get the correct ADU level, and it starts capturing the 25 images. The problem is that it doesn’t index the file names so I only end up with one image. If I enter the specific time for the flat that gives the 28000 ADU, it works as expected and indexes the images. Has anyone else experienced this, if so what do I have set wrong?
Equipment - RPi4 4 GB, LED tracing pad for flat frames.

I have just started to use the scheduler so this could be my error but I'm not sure what's wrong or how to fix it.
The last four times I have been imaging I have used the scheduler so that I can actually get some sleep. Each time I have gotten the same error that ends the imaging session. This happens even though the session isn't complete (last night it was on image 88 of 120) Below are the last several lines from the log file.
If it matters, I am using an HEQ5 (EQMOD driver), ASI178mm imaging camera, and SSAG autoguider. I'm running Astroberry on a 4GB Rpi4 and accessing it via VNC (faster response)

Unfortunately I won't be home until Saturday to review what my settings were for this run. I'll post it then.
As far as the periodic error, I wondered about that at first but I thought that would be demonstrated by a gradual drift in one direction followed by a drift in the opposite direction as the worm wheel rotates. That doesn't appear to be the case here.

Last weekend was my first attempt to use the internal autoguider since I usually use PHD2. I saw that I could export the guiding data so being the geek that i am, i downloaded the from the 100 minutes of capturing M27. During the imaging session I was capturing 1 minute subs. When i opened the data and charted it in Excel I noticed there was a significant spike in the RA error every 10 minutes of the capture session. Any idea what I should be doing to correct or at least minimize this? I am using an older Meade LXD55 mount if that helps.
