Guide objects not disappearing if created via copy and then undone

Hi, there is an intermittent bug I keep experiencing that relates to objects turned into guides.

Steps to repro:

New document

Draw rectangle

Right+click (ensure object is selected), Select > Make Guides

With Selection tool (Black arrow) selected, Alt+Drag the new guide object elsewhere on the canvas and release to create a duplicate.

At this point confirm in the layers panel that there are two objects in the scene now.

Undo your action - this should leave one object in the scene, as shown in the layer panel, but intermittently a 'copy' of the guide object will remain on the canvas, but it will be unselectable and not appear in the Layers palette.

It will also be visible in the Outline view, but still be unselectable.

The only way found to remove the duplicate(s) so far is to close and reopen the document.

You may even be able to undo so many steps that the object used to create the guides is not longer in existence, but the duplicate guides still are.

Obviously, this is not great for working - a load of guides that don't work clogging up the viewport isn't great for productivity.

Video attached showing the results I've been having anlong with steps taken to repro.

Cheers,

Mike
