Dynamic blocks not working in 2025 SP2

I upgraded from 2025 SP0 to SP2 and have noticed dynamic blocks that used to work nolonger do - I don't have the grab handles for adjusting size. 

 

These blocks were created in Autocad but have always worked in DraftSight. 

 

I also used to get a warning about losing the dynamic functionality if I tried editing these blocks. I don't get this anymore.
