Selection/display bug when moving a pasted path in Glyphs 3

[man_instripes (Tamnekojapan*3302)]

Please help,

I am experiencing a possible selection or display bug in Glyphs 3.

When I copy and paste a circle path and then try to move the pasted circle, Glyphs displays blue connecting lines between the nodes and another point outside the shape. The background contour also appears to become connected to or selected with the pasted circle.

Please help, thank you

I did try to do that but it’s still the same

I don’t understand the issue. What is wrong?

I just want to move the top circle without moving the bottom circle.
However, whenever I double-click to select the top circle, the cursor somehow selects an edge of the bottom circle, and therefore I can’t move the top circle without touch the bottom circle.

When you click close to the top circle (e.g. at the top edge), it selects the bottom circle?
