I solved that by filing off the machining ridge left on the threaded end of the bolts or by adding a washer under the bolt head.
Actually its the bolts that screw into the end of the 20x20 extrusions.

I think I may try to find slightly shorter M5 bolts. I don't have the tools to do any tapping. If I can't find the bolts, I'll reach out to Colin.
