Heavy Duty/Jumper Cables No longer attach to second vehicle

I’ve tried on two computers, multiple saves, and multiple worlds. I can connect my heavy-duty cable or jumper cable to the first vehicle but not the second. The only option I get on the second one is ‘detach and re-spool cable’. This started happening in the last couple of days. Is this a known bug?

edit: using [Build #9596]

edit2: fails on build #9587 and later, everything before that works fine.
