Clear the BSS138_ZTX.asy symbol's "Modfile" attribute.

how and where do i do that exaclty

Edit the symbol file "BSS138_ZTX.asy".
Look for the "Modfile" attribute, and remove the value.
Save and close.
Open the schematic, remove the symbol, then re-add the symbol.

You must have used "create symbol" function to automatically create a symbol using a .subckt definition. When the symbol is created, the symbol file is placed in the autogenerated folder and the absolute path to the subckt file is auto populated in the "modelfile" attribute of the symbol. I always remove the "modelfile" value because it causes more problems for me than it solves.

Attached is the symbol with the "modelfile" value removed and the pins renamed. Save it in the same folder as your schematic.
Then remove and replace the symbols on the schematic with the modified one.
Make sure the BSS138.txt file is located in the schematic folder, and add this directive to the schematic:

.inc BSS138.txt
