I can't edit/update exported text lists with the latest professional edition of Passolo

Hello,
we use the collaboration edition (Version 18.0.109.0) to export translation bundles to be used with the Passolo TE. Using this version of the collaboration edition allows us to update and change exported textslist, what exactly is what we expected.

Now, we bought another Passolo Professional Edition (Version 18.0.116.0) license to edit the projects created with the collaboration edition. But, as soon as a textlist is exported, it is no longer possible to update or edit a single Text.

That is strange, as the collaboration edition allows the editing of exported textlist and renders the professional edition kinda useless for us. Is this due to the newer Version? Is this a bug or on purpose? I would be glad about a helpful answer.
