Have you tried upgrading to core 2024.7.1? I can't check the earlier core version, but the latest one works fine for multiple stations that I've tried.

FWIW, I had this issue in 2024.6.x, and it is indeed fixed for me in 2024.7.1.

[MatthewFlamm]

It is also fixed for me in 2024.7.x. Will close this based on multiple reports of it being fixed.
