Issue seeing or adding pan adapter slice

I am running a Flex-6500 with SmartSDR 3.3.32. I have had the new microSD card installed for a couple of months with no issues. This afternoon, I lost my pan adapter slice flag and I cannot add another slice. There are signals visible everywhere (20 meters) but I cannot click on them or hear them. SmartSDR CAT says the slice is not present for my selected com port and SmartSDR DAX says No Slice or Off on any of the RF streams. I cannot turn them on. I have done a hard reset of the 6500 and uninstalled and reinstalled Smart SDR 3.3.32 but not joy. I even opened the 6500 to ensure the microSD card was seated properly. Any ideas on what to try next?
