ok, i found a workaround if you ever start having this problem. here is what i was able to come up with:
1 - the copy of the teleport marker seems to be linked to the original. so, if you chain them, copy 1, then copy the copy, and etc, they are all linked. delete one of them, recolor it, or whatever, then all of them that are linked are changed. so only make the one copy for the other end. for the next one you need, create it all over again - but set it side by side with the original so you get the same dimensions.
2 - moving them is not as bad as i thought. select the one you want moved and go to where you want it move to, the widget will grow so you can still see it, no matter how far away you are. Grab the bottom plane and drag the teleport marker to you, it does not leave copies along the way.
there you have it, worked for me, but then the problem showed up for me too, so maybe they both are just screwed up lol
