PMM Component Error when creating Service Schedules

When creating a service schedule we are receiving a component error (image attached).  We have been working with our consulting team and they can't seem to make heads or tails of it either.

This issue started occurring after our org was updated to Winter '24, prior to that it was working without issue.

We have come across an existing KB article but the work around doesn't resolve the issue (tried on multiple browsers, clearing cache, incognito mode after making suggested change)

Anyone else running into this and the above work around isn't working?  Our consulting partner is looking at opening a case with Salesforce, but figured maybe someone in the community has run into and resolved it.

Thanks in advance!
