Spurious handi-selection markers on diagram

I have a number of handi-selection markers on my diagram (see image). How did they get there and how do I get rid of them?

Restarting Visual Paradigm got rid of them.

Hi KDean,

Thank you for your post and sorry about the problem. Are you able to recall the steps?

Best regards,

No, sorry. If it happens again, I’ll see if I can replicate and let you know.
