Bug Description

If I call the /context command, I see I have plenty of context available (80%), but then on the bottom right you can see context is at 0%. See image.

Basically whenever I /clear all the context, it gets immediately reset to 130k+ tokens with a simple "hello Claude". The issue is real and not only visual, as then I get a 400 because of context exceeded. This discrepancy seems a bug, but have not been able to solve it in any way (logging out, uninstalling, changing project, etc.)

Steps to Reproduce

1. Run /context command
2. Compare with context left on the bottom right
3. Note the discrepancy

Expected Behavior

Context values should match between /context command and bottom right display

Actual Behavior

Low context shown in bottom right when /context shows plenty available
