Navigraph loads LOWI LOC R when LOC DME EAST is elected

i use charts deskotop Win10. using the latest version.
when i select the approch LOC DME EAST (LOWI) on my loaded flightplan (from simbrief), navigraph automatically selects the LOC R approach and pins that chart instead of the selected LOC DME EAST.

i have this issue over and over again, already since a long time (approx. a year).
Seems to me as a bug.

if i select LOC R as approach, LOC R is loaded/pinned.

here is a video of the issue described above.
