SF - Special Function definition line gets lost

[Ralf-W]

Is there an existing issue for this problem?

• I have searched the existing issues

What part of EdgeTX is the focus of this bug?

Transmitter firmware

Current Behavior

I define a SF to reset the ALT reading of my variometer.
No problem with setup and use of this SF.
However, when I try to edit this SF, the input line addessing the ALT sensor is missing.

Expected Behavior

I expect to be able to edit an existing Special Function.

Steps To Reproduce

Define a SF, e.g. SF11, to reset the ALT sensor reading to zero.

Test this SF11: It does work as expected. Fine.

Try to edit SF11: The third line, defining which sensor to be reset, is missing.

This problem does NOT exist, if I reset Telemetry, or Timer1, etc.
But in combination with the ALT sensor, the third definition line is missing when editing the SF definition.
