Vehicle welding rig not working

After updating to build 10622, the welding rig I’d been using as part of a vehicle now gives the “Your tool does not have charges to do that” message anytime I try to use it, despite multiple charged storage batteries in the vehicles. Other powered parts of the vehicle are functioning & drawing from the available batteries just as they’re supposed to.
Anyone else encountering this? Thanks!

Build 10771, same problem.

“Needs 5 charge but has 0” despite having fully charged batteries installed.

Edit: Seems like I can still use it for crafting, it’s just trying to use it after pressing ‘e’ on it that it gives that message, making me not able to use it for repairing things.
