LEGO Beams "All Straight" hole alignment issues

Aloha,
We are creating Tetrix FTC robots using Solidworks and the Tetrix/LEGO Parts libraries from 3D Content Central (also downloadable from within the Solidworks app).

We are having problems mating one particular LEGO part named "All Straight". This is a very handy part because the one file is used to create LEGO beams in all standard lengths, e.g., 3 hole, 5 hole, 7 hole, etc.

Unfortunately, the hole spacing in this part appears to be slightly off compared to other LEGO pieces. The All Straight beams mate to each other (using two concentric holes) with no problem. But, mating to other LEGO parts (using two concentric holes) does not work. Of course, mating to other parts with a single concentric hole is fine. But attempting to mate a second hole on the same beam results in the following error:

"The default mate type (concentric) would over-define the assembly. Please select the mate type below"

Has anyone else had this problem?

Thanks, in advance, for your suggestions.
