Proxy notice showing on all drawings created in an earlier revision of Draftsight

I've recently updated to the latest 2024, SP1 & now SP2 - but am having problems with a proxy notice displaying on opening ANY Draftsight drawing. What's been removed from Draftsight?? - as all the drawings I'm opening that I've previously created in an older revision of Draftsight, are all showing this notice - even the simplest drawings, such as a straightforward border template. It's really annoying. How can I either adapt the drawings / find what is causing this issue - or turn off the notice for good? I've tried using a fix from an earlier question in the group - but that command is already set to 0. Maybe it's a software issue they should be made aware of?  Any advice gratefully received!!
