loner, I had similar if not same probs, but saw post somewhere here that recommended going to TiBu's Prefs, Backup Folder locaeion, & going to the pick bar for 'Storage Type' ]ust above Tibu's Detect button, choose Document Provider & I found it left it @ External Storage & I just hit Detect fm there, & it 'found' my directory w/Tibu backups & after closing & reopening TiBu I've been back in business, able to have TiBu see my card… & TiBu backups in TitaniumBackup Dir of my microsd card.

There may be something that requires you go to root of card & hit Select button on lower R of screen, but its late & that may be coming up in my mind as a requirement for granting access to Solid Explorer & the ilk when 1st trying to do a File Manager type task I.e. copy or moving files… but
it could be an issue here as well- I'm happily protecting my user/system apps w/TiBu & using backed up apps to delete the main app, re-d/l w/PlayStore. & restore my data W/TiBu restore to confirm I had a buggy version of the app...

HTH, oldwolf
