Can't enable "Disable RT Startup App" using NI System Web Server

[chauser]

Describe the bug
The NI System Web Server has a box to check to "Disable RT Startup App". After checking the box and clicking "Save" at the top of the page, then refreshing the page, the box is again unchecked (and the setting has not taken effect).

To Reproduce
Steps to reproduce the behavior:

1. Connect to a roboRIO with a running NI System Web Server
2. Check the box "Disable RT Startup App"
3. Click "Save" at the top of the page
4. Refresh the page in the browser
5. Observe that the box is no longer checked.

Expected behavior
The setting takes effect and its correct status is shown on the web page.

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

Desktop (please complete the following information if applicable):

• OS: Windows 10/11
• OS Language: English (Chrome browser)

roboRIO (please complete the following information if applicable):

• roboRIO 1 or 2?: roboRIO 1, not checked on 2.
• Image version: FRC_RoboRIO_2025_v1.0

Additional context
I observed the same behavior with 2024 RoboRIO images.
Workarounds: use the startup settings control of the roboRIO imaging tool or press the USER button on the roboRIO for 5 seconds. Note that the web server shows the startup app status correctly when it is set by either of these methods. Also, the setting can be cleared using the web server once it is set by one of the other methods.
