Incompletely Passolo bundle imported into LPU team version and strings released - Can't import updated Passolo bundle

I had a Passolo project going into various languages.
Our DA translator sent back her bundle which I assumed was fully translated. However, it ended up being either an old version or she just didn’t do the work right.
Anyway, I imported that bundle RELEASING the string list.
Then she came along later with an updated delivery that did have everything translated.
Obviously I couldn’t reimport that anymore.

I tried exporting a DA bundle again and seeing if I could re-import the bundle from our DA linguist taking that slot but it didn’t work.

Does someone know how to resolve this?
