Hi, I'm having issues with my locators. I've set all locators and then it automatically calibrated. When I come back to insert  promitives, one of the locators has lost it's designator and cannot be used as a place marker (see attached screenshot). This is common on almost every locator. Two of the screens show the number while the third only shows a red square. When we try to place a corner, it goes in completly different places. Does anyone have  an idea what went wrong?
