We're having problems reading gf180 def files with klayout

When opening inside klayout by reading the lef and def, klayout complains about the fact that there is no such
```_endcap```
 cell in the LEF file, but it is there

using the open_design script in openlane/scripts/klayout

we get this error `
```Warning: Reading layer map file /pdks/gf180mcuD/libs.tech/klayout/tech/gf180mcu.lym, line 30 not understood - skipped```
`

Anyone else seeing this? Where would be the right place to open an issue - on the PDK itself?

Our team developed a docker container with gf180mcuD and it's working. This is our [patch script](<https://git.1159.cl/Mario1159/osic-stacks/src/branch/main/stacks/chipathon-tools/scripts/patch-open-pdks-gf180.sh>). We use volare to install gf180, and then we download efabless gf repo to get some dependencies and a dropdown menu.

What is Linen?
