@ Zbigniew Wolanski, That's correct - the signal field names in Data Inspector are read-only by design. It is a pretty common frustration. If you need different names, you will have to rename the fields in your original data before opening the Data Inspector.

Hi Zbigniew,
To modify a signal field name in the Simulation Data Inspector, double-click directly on the signal name and type a new name. The updated name will then appear in the Data Inspector for that logged signal.
For more details, please refer to the documentation:

Hi Zbigniew,
I tried to replicate your problem on my end with a simpler version and I am attaching the file for your reference. For a better understanding of the issue, it would be helpful if you could share your files as well, so I can help you more effectively.
Hope this helps!

Thanks. I tried your file in R2024B. It seems to work, doing what it supposed to do (names can be changed)
Have look at my test though. The signal shown by the red arrow cannot be edited, All three plots representing consecutive runs have the same signal namess "NanoCore.Tests.Wn_Pri.v" and the box representing the signal name on the left isn't editable. These tests were ran with varying Nw and it is difficult to tel which plot represents which parameter. I hope the model
