Media Bay not finding vstpreset files that do exist

I have had this problem in the past, but never came up with a solution.

Scan MB, it finds three of the seven files in the C:\Users\Jeff\Documents\VST3 Presets[jBridge]Audio Ease\Altiverb6_64 folder. If I r-click on one of the files in MB, and ‘Show In Explorer’, the folder opens, and I see the files, but a rescan of MB does not find them. Trashed prefs, same thing.

Anyone have a fix for this?

Thanks in advance.

Do they show in VST Sound- User Content at the bottom of MB, Jeff?

No, not there.

–edit–

Ok, more info.

Load an instance of Altiverb
Save preset, using filename of an existing preset
‘File exists’ dial box opens
Choose to overwrite
That newly created file is unavailable
Save preset, using unique filename
That file becomes available immediately

What am I doing wrong?

Any ideas here?
