**Steps to reproduce:**  
In this case the problem occurs in the Move tab, when opening the ‘Tool position’ tab by press any value in the top right of the move tab.

 ![Open Tool Position](https://us1.discourse-cdn.com/flex020/uploads/universal_robots/original/2X/9/96e8e2247ed6dd18f55bef0c2a730d7188149dbd.jpeg)  
And selecting RPY[rad] or RPY[0] in the dropdown menu above RX. See the picture below for the first values in RX, RY and RZ  
 ![First value](https://us1.discourse-cdn.com/flex020/uploads/universal_robots/original/2X/d/d9784e4f77e9ee7a8caff2e8101313de663261a7.jpeg)

If you press cancel to exit this window and open the window again there will be different value behind RX, RY and RZ.  
See the picture below for the different values in RX, RY and RZ

 ![Second value](https://us1.discourse-cdn.com/flex020/uploads/universal_robots/original/2X/f/f77993affe46c9e90931d3064a7bac229ec13fe9.jpeg)

(Only happens when selecting RPY[rad] or RPY[0] in the dropdown menu)  
From what i could test its working correctly in version 5.15.2

**Expected Behavior:**  
The RX, RY and RZ should read the same value every time the tool position window is opened

**Actual Behavior:**  
Everytime you open the Tool position tab there is a different value behind RX, RY and RZ.

**Workaround Suggestion:**  
No workaround found at this moment. The first values that are shown seem to be correct, the following not.
