Gondolas spawning inside each other

[jpeter772]

When i have a gondola running, it works just fine. But when skiers go inside the station, they start spawning in two or threes inside each other. This means they break, distort the cable and skiers can't get on, so I cannot use gondolas. I am playing the game on MacOS Sequoia 15.2. Is there any way I can stop this? It has only just started to happen each time.
