Weekly recurring items not showing up on the timeline

I’ve just noticed that I had a recurring items to do only on Tuesday, Thursday and Saturday but it didn’t show up on the timeline. When I tried to change the starting date it showed on the timeline but just for that day, not showing the other days(example: I changed the starting day to Tuesday and it showed up on the timeline, but there wasn’t on Thursday or Saturday). Also not items specific, happens also for the other weekly items I have
