I think to have found a bug related to the management of the symbol file name and the field Value in the Symbol Editor.
I was looking to understand why changing the Value in Symbol Editor changes also the symbol name (that in my opinion is very very wrong). So I tried to manually change the content of the corresponding lib. I reported above the original and the modified text relevant part. Line F1 contains the modified text:
original:
R_1K0_R0402
DEF ~R_1K0_R0402 R 0 10 N N 1 F N
F0 “R” 50 25 50 H V L CNN
F1 “R_1K0_R0402” 50 -275 50 H I L CNN
F2 “LibPCBnew:R0402” 375 -350 50 H I C CNN
F3 “C:\Dati\Micron\R&D\Datasheets\Resistors\Multicomp-MCMR04X435_JTL-datasheet.pdf” 1650 -475 40 H I C CNN
F4 “1/16W” 50 -125 50 H I L CNN “Power”
F5 “1K0” 125 -50 50 H V C CNN “Component Value”
F6 “50V” 50 -200 50 H I L CNN “Voltage”

so… seems to me that the Symbol Editor GUI takes the dats from the DEF line instead of F1 line to update the Value field. Unlink this management will help also to pass the correct Value to the Spice Value field (Edit Spice Model/Passive/Value).
