I found an issue if trying to open in RH7 a file exported to v7 from Rhino 8 SR0 2022-8-30 (Rhino WIP, 8.0.22242.00306, (the issue is present even if trying to export using v6 formt from RH8)
the layer state panel seems populated but names are blank like in the attached screens:

Tried both with MacMini and MBP M1 and it’s persistent.
