Why can't I see the same, common Custom Properites from a selection set of blocks?

Hello to all:

Pleasd reference the attached files.  I have a lot of dynamic blocks that share what should be the same-named Custom Properties.  My end-users want to be able to change the same property in multiple blocks...but for some unknown reason, I can't get the property switches t0 remain visible when multiple blocks are selected.

For example: The attached files has two groups of blocks.  When I select the first two blocks, the properties I want to change ARE selectable: SWITCH: DUST COVER TYPE and SWTCH: DUST COVERS

The same thing happens when I select the next grouping of six blocks.  HOWEVER...any selection that takes from BOTH groupings results in the SWTCH: DUST COVERS not being selectable.  WHY is this?

Your "Switch: Dust Covers" Lookup Parameter in your block R9.1.2 (02) 24Z_RSH has an extra space at the end (see the image below). Delete that space and it will show up
