I have read all kinds of support posts here, but I'm stuck.
Here's my issue.
I used to have two cache NVMe drives in my RAID1 cache pool, the first being 1TB and the second being 2TB with RAM.
I physically removed the first drive and rebooted as I wanted the full 2TB capacity available. In my setup I don't have the need for cache redundancy.
After removing the first 1TB drive and rebooting, some rebalancing (don't quote me on this) started and finished.
Currently my UNRAID setup works fine, but I my first cache slot show as "Not installed". When I reboot, I have to manually start the array to get everything online.
So: My wish is for the first cache slot disappear. If I stop the array and try to reassign the second "Cache 2" drive into the slot "Cache" says that the drive will be erased. This makes me afraid. I am unable to change the number of slots to 1 — the lowest number available is 2.

I also have a diagnostics zip available but don't know how to upload.
