Cursor IDE agent window stops showing model and turns on "Fast" by default

Describe the Bug

In Cursor IDE agent window next to Agent/Plan/Debug/Multitask/Ask mode indicator, the model indicator stopped working. Instead of showing Composer/GPT/Grok etc. it shows only something like “High Fast”. It also turns on fast mode for projects, where I did not do that as a user.

Steps to Reproduce

Update Cursor IDE and open a previous project with a specific chosen agent model and fast mode disabled.

Expected Behavior

Keep project agent as selected by the user before. Show model. Do not turn on fast mode without user permission.

For AI issues: which model did you use?

Exactly this is what the cursor GUI stopped to display.
