Reset to Defaults does not fix the fields.

Also, it changes the Transmission line type. And this is the last thing the user is expecting. It has to change the values only.

[johannespfister]

A yellow box just means no valid value input (no value, or a value <=0 or <0 (depending on the field)) and a red one means it couldn’t be calculated / NaN (Not a number). This is why resetting the values works.

The problem is that with your theme the nan is white/bright gray, which is problematic on this bright red background.

Edit:

Checked the source code. The background colour is set in TRANSLINE::setErrorLevel(), in ./pcb_calculator/transline/transline.cpp . The text/foreground colour is not set and probably depends on your theme.

It is not my theme. It is dark theme from Kicad.
