Physical printer: Print Host Type keeps changing

[tonerod]

Description of the bug

I'm trying to setup Prusa slicer to print directly to my printer (Ender 3 S1 Pro running Klipper). Everyting goes well in the setup, including a "Test for connection", but when I click "OK" which closes the "physical printer" window, and I open that window again, all my settings are still there, but the "Host Type" keeps switching from what I seclected (Octoprint) to FlashAir. I can't get it to stay on "Octoprint" Just as a test, I tried seclecting each of the other "Host Type" in the dropdown box, and saving. Each one of them remain as I selected them, except "Octoprint"

Note. The process works fine when I set up my Prusa i3 mk3

Project file & How to reproduce

1. Edit "physical printer" under printer setting
2. Fill out all the required fields, (seclect "Octoprint" as host type).
3. Press "Test" to check for connection... receive message "Connection to Octoprint works correctly"
4. Hit "OK" and window closes
5. Open window again and "FlashAir" is now in the "Host Type" field.
6. Can not get "Octoprint" to stay as "Host Type"

Hello, thank you for reporting.
I can confirm, this bug is happening at my side too. We will look at it.
I also checked and after point 4 - PS should be entering code for Octoprint upload. So uploading should work (until you re-enter the dialog.) Anyway it needs to be fixed.
