Referee scoring bugs with Amazon Fire/Silk Browser: Unable to submit AUTO scores unless both alliance robots are marked as present.

**Describe the bug**
It is impossible to submit scores from the AUTO period (and thus score the rest of the match) unless both alliance robots are marked as present in the Amazon Fire/Silk Browser environment.

**To Reproduce**
Steps to reproduce the behavior:
1. Sign in an Amazon Fire device to FTCLive with referee permissions using Silk browser (the default browser).
2. Load a match in FTCLive (either a test match or live match should work) using a device configured with scorekeeper permissions.
3. On the pre-match setup screen select on the Amazon Fire, select one team to a state other than present. The bug seems to affect selecting either "no team" or "no robot".
4. Attempt to play the match.

**Expected behavior**
A referee with an affected device should be unable to select the location of the robot whose team was selected as "no team" or "no robot" during the auto period, and the scoring system will not allow them to submit auto scores at the end of the period. Accordingly, the affected device is unable to score teleop unless the referee edits pre match setup to indicate both teams present, and assign an end of auto period location to both teams.

**Screenshots**
If applicable, add screenshots to help explain your problem.

**Device (please complete the following information):**
- OS: Fire OS (Android)
- Browser: Amazon Silk
- Version: Fire OS version 8 (built on Android 11)

**Additional context**
Possibly related to separate issue in which zeros do not autopopulate in chamber, basket, and net zone score selection windows.
