menuconfig --release true not saving changes

[usbalbin]

I have created a project using

cargo generate --git https://github.com/esp-rs/esp-idf-template cargo

Running cargo pio espidf menuconfig works fine and I can see the saved changes in the UI from last time. Compiling the code (cargo build) also works and I can tell the changes are in effect. I can also see that my_project_root/sdkconfig.debug is updated.

However when I try to switch to release mode, thing works less great.

Running cargo pio espidf menuconfig --release true does not produce a my_project_root/sdkconfig.release. When running the command multiple times the changes seems to not get saved. Compiling the code using cargo build --release does not seem to be using my changes.
