What's the proper way to look at the drc mag files ? I start magic with

magic -rcfile path/to/sky130A.magicrc  usb_sky130.drc.mag

but then when loading I have thousands of :

Duplicate cell in usb_sky130.drc:  Instance of cell sky130_fd_sc_hd__decap_3.mag is from path /home/tnt/sky130/openlane_workspace/openlane/designs/pyfive_no2usb/runs/test_diode/results/magic but cell was previously read from ~/sky130/openlane_workspace/pdks/sky130A/libs.ref/sky130_fd_sc_hd/maglef.

It eventually loads but it takes a while to print all those warnings.
