Osnap goeas wonky near Leader arrow

Rhino6 on Windows 10 box. Attempting to copy a series of objects using Intersection Osnap. Works fine until the cursor gets near the arrow of a Leader line. Then, no osnap hints show, only a red circle with slash.

What’s up with that?

Hello - I don’t see this so far, in either model space or a layout - can you post a file with the minimum objects that shows the problem?
