Glad you got things corrected.

AH! That was the key - I didn't select the ENTIRE library. Thanks!

You have to find the mis-spelled entry(s) in order to correct the data. My directions are probably not the best, but try this...

Enable 'Column Browser' - From top menu select View > Column Browser - it will should appear at the top of the track list.
Make sure one of the columns showing is 'Album Artists' (should sort automatically as files are loaded in next step)
In the left tree select 'Entire Library' and all your tracks should start populating in the right view pane.

All 'Album Artists' will populate in the Column Browser. There you can scroll through and find any thing out of place such as mis-spelled entries. Select any 'Album Artist' you want to edit and they will populate in the track list below. From there you can use the 'Properties' editor to fix any errors found.

I try to be very careful entering data and I'm usually surprised at the number of errors I find when checking.

Also, you can use this method for any fields you can select in the Column Browser. I leave Column Browser open all the time, comes in handy for lots of things.

Sorry to say it didn't work. I performed the following steps:
Sorted by Album Artists
Selected ALL of them
Opened the meta tag editor
Replaced the contents of the Album Artist field with the correct spelling

If the list of suggestions is based on previously entered data, then this should have gotten rid of the incorrectly spelled item. But, when I added a new song and went to enter Various Artists in the Album artist field, the incorrectly spelled item was still there. Damn! I thought that might do it.

Thanks, I'll give it a try.

I think those pop-up items are dynamic and only show items that are actually used, so it's in use somewhere in your data.

If I have an entry like that, I find where it's used and make corrections. Then it no longer shows in the pop-ups. Using 'Columns' and viewing files from 'Entire Library' is one way to find those entries, also works for other data fields.

I have a couple of instances of bad meta data entries. For example, when entering Various Artists in the Album Artist field, MediaMonkey pops up a list of suggestions. One of those suggestions is a misspelling of Various Artists. I'd like to delete that particular suggestion, along with a few others that appear in other fields. Is there a way to do this? TIA for any help
