When resizing Pool in BPMN editor the text stretches instead of resizing correctly

So in my testing whole Pool is acting weirdly. When I create it, I can click on line and resize it (it's stretched as in original report). When I change number of lanes and click outside of element, I can't click on the line to resize it or move it again.
And also when I resize the Pool, save the project, close the project and open it again, the pool is not stretched anymore, but it's in default size and bounding box is what it was before closing. First screenshot is before closing and second one is after reopening it again.
