Mergin Queries - Bug?

Hi all,

I have a really annoying problem:

I'm trying to merge two queries and can't get the columns to match... to illustrate the problem I have reduced my tables to only two columns each and only three rows. Please see pictures:

Table A

Table BI press "Merge Queries as New" and select Col 1 for both tables. No mather what options I choose from the "Join Kind" option I get 0 matching rows... Please see the next two pictures..Zero matches!!!

 Zero matches!I believe this is due to some kind of formatting error but everything seems okay to me. Does somebody have any suggestions on how to trouble shoot this error!?

Thank you!!
