Looks like it's probably a duplicate of #22485.

Actually it appears to still be an issue and was reported in #22563. I've accepted that ticket.
Note:
See TracTickets
for help on using tickets.
Added some formatting (please use preview). I think a minimal set of models to reproduce the issue would be more helpful than the information you have provided so far.
