"Ignore streaming service setting recommendations" checkmark does not seem to work

Platform

Operating system and version: Windows 10 2004
OBS Studio version: 26.1.1

Expected Behavior

Checking "Ignore streaming service setting recommendations" should work. It doesn't since I choose a rate control of CRF for Twitch and it is still set to CBR. I have noticed that the setting "ApplyServiceSettings=false" is missing from the [AdvOut] section of basic.ini. After manually adding "ApplyServiceSettings=false", the rate control is finally set to CFR.

Current Behavior

Checking "Ignore streaming service setting recommendations" adds "IgnoreRecommended=true" in [Stream1] section but does not add "ApplyServiceSettings=false" in the [AdvOut] section of basic.ini. I'm not sure if is suppose to be there anyway since maybe it's a bug that the new flag "IgnoreRecommended=true" does not work.

Steps to Reproduce

1. Install OBS
2. Start OBS
3. Skip wizard
4. Click on Settings
5. Log into Twitch in Stream section
6. Check "Ignore streaming service setting recommendations"
7. Goto Output section and change Output Mode to Advanced
8. Change Encoder to x264, change Rate Control to CRF, make sure CRF number is 23, change Keyframe Interval to 2.
9. Click Okay and start streaming
10. Goto View -> Stats and notice the bitrate is 2500 kb/s instead of under 100 kb/s since you are streaming a black screen.
11. Check logs and see "rate_control: CBR" under "[x264 encoder: 'streaming_h264'] settings:"

Reproduce the issue on Windows 10 with OBS 26.1.1 using the listed Twitch and Advanced Output steps. Compare basic.ini's [Stream1] and [AdvOut] sections, then inspect the log for the reported rate_control setting. Done means the ignore recommendation option preserves the selected CRF setting and the resulting configuration and log reflect it.
