Hi again,
Thanks for taking the time to review the questions.
I thought one of those would help understand what could be causing the issue. It could potentially be related to the data coming from a feature class in a local file geodatabase but you will probably need to confirm this with a member of Esri Technical Support.
I would raise a support case as it might be possible to send across a copy of the data to a member of the Esri Technical Support team to investigate.
In the meantime, I'd try adding a layer from the Living Atlas and seeing if the same issue presents itself.
Apologies I couldn't work out the direct cause despite the answers to those questions.
