Copied & moved button loses its icon and macros

Serengeti (Rhino WIP)

using 8.0.23108.14305 on win11; upon opening rhino, I saw this:

what I had done in a prior session was to copy a button and change the macros, and then I moved it:

but now it has no icon and no macros; so let’s try to repro that – ctrl+drag a copy of the viewport props button and edit its macros:

I think I have seen it mentioned before about the right-button macro not showing correctly until re-opening the editor, so let’s ignore that and just confirm that the commands work:

now shift+drag move the new button:

seems to have worked, and the commands still work:

however, in the command line I see printed errors like these, maybe dozens of times

and when I restart rhino, the new button has the wrong icon:

and no macros:

the toolbar I’m dragging into is from my plugin’s .rui, which is installed next to my plugin, but which rhino 8 is not automatically opening like rhino 7 does, so what I had done was to click in a toolbar area > show toolbars, choose bella_rhino from the RUI Files dropdown, and show & dock its only toolbar as shown in the screenshots; here is that .rui extracted from my plugin installer:
