saving changes from pin planner

Hi Alex im using Quartus version 15. And no i don't have the .qsf file open in any editors.. if i open the "node finder" alt+1 in quartus all the signal and notes are there, but in the pin planner they are all listed as unknown... okay ill look and see if i can find any program holding the .qsf file. But when i look at it in a file explorer it gets updated (new timestamp) when i close the pin planner.

but i dont seen any updates in the file when i compare it to the old one. They are not binary equal, as a line shift is added, but nothing else is added. Im trying to make PSB_ENA an output what should i see in file ?

the following is what i can find with PSB_ENA in the .qsf file

set_location_assignment PIN_101 -to PSB_ENA
set_instance_assignment -name CURRENT_STRENGTH_NEW 16MA -to PSB_ENA
set_instance_assignment -name SLEW_RATE 1 -to PSB_ENA
set_global_assignment -name ASSIGNMENT_GROUP_MEMBER PSB_ENA -section_id "U1-7(output)"
