When two analysts work on the same AR, then the one that saves second clears out the values saved by the first.
1. Open the same AR on two tabs - you can also reproduce this by opening the same AR on two PCs.
2. Enter results on the first tab and submit it for verification - making sure you only tick what you entered.
3. Do the same on the second tab but for different tests.
4. Now refresh and you will see that everything was entered in the first tab is now blanked out.
I've attached the same process in screenshots.
