My WD "My Passport Ultra for Mac" reverts to APFS after I set it to Mac External (Journaled)
My WD "My Passport Ultra for Mac" reverts to APFS after I set it to Mac External (Journaled). After what appears to be a successful ERASE and format as written in my previous sentence. If I go back to Disk Utility, it will say the external disk is an APFS. Is this OK? It appears to work with my Time Machine backup. BTW, my Apple is a Mac Mini M1 2020 using OS Monterey 12.0.1. In concert with the addition of this newly formatted external used for Time Machine, my computer or my old, but still perfect picture "Thunderbolt Display" (one or the other) has been going dark randomly, and showing what look like selection, highlighting, of desktop items ghost thru. Are these issues related.
