[Plugin: VO Store Locator – WP Store Locator Plugin] Edit loses tag

VO store locator standard.

I have two tags defined.

I create a number of listings (by hand), selecting a tag for each.

Go to VO Locator listings.
Click edit.

Quite frequently (but not always), the tag drop-down reverts to “–select tag–” rather than the tag that is defined in the database.

This is painful as every time I edit, I need to remember to reset the Tag value.

Browser is Chrome (inogntio, if it matters.)

I don’t see a pattern in when the tag is properly selected and when it’s not…
