Lock code manager - broken?

My lock code manager has been flaky for years. Every time we have company I fight with it trying to add codes for temporary guests.

Trying to add a user/code and it's just sitting there showing pending jobs-2. It added it to one lock but not the other. Verbose logs show it getting codes from both locks then thats it.

To get by I manually added the new user/code in the slot it should be in. Even refreshing job status still shows pending jobs - 2.

usually this indicates a communication issue with the lock. Have you tried adding codes directly using the lock driver directly to verify the issue is or is not related to LCM?
