Lumetri Color Hue curves - vertices snapping together

Lumetri color works fine when you have 3 or more vertices - no problems here.

But when you have just two vertices - weird thing starts to happen.

If you have two vertices on the curve, and you drag them too close to eachother they suddenly snap together to the same horizontal position and after that there is no way to separate them. You can't even move them horizontaly just vertically.

Again this immediately stops when you add a third vertex.

It works similarly in Premiere except in Premiere it bugs out only when you try to move the left vertex near the right one. If you grab the right vertex and move it towards the left one, you can even drag it beyond the left one and nothing happens. You can drag it wherever you want. But if you grab the left vertex you can just drag it towards the right one and the moment they get close together they will snap together and at this point there is no way of unsnapping them.

Can anyone confirm this?
