Although the scenario is not quite as described in the SOL it does look like you are running into the bug described in AskF5 Solution SOL15767.

 

That's fixed in 11.5.2 and onward; depending on your configuration the workarounds may also be appropriate.

 

If not that then I would humbly suggest this is a question that might be better asked via F5 Support who can help you review your configuration for any other issues and look at diagnostic data from the device in order to troubleshoot the configuration sync process.
