Filter disables TM


Created two filters in Project under all Language Pairs - Translation Memories - Filter based on User that last worked on the TU

In Editor, when the filter is used, there are no hits from the TMs - even in Concordance Search mode.

Error message: An error has occurred while using the translation provider NAME OF TM: Object reference not set to an instance of an object.

This is repeated for all TMs used for the specific language pair.


In Project Settings, the relevant TMs are enabled, also for Lookup and Concordance


SDL Trados Studio 2017, GroupShare.


Any ideas where I should start looking for a solution?
