Past league seasons not appearing

Greetings.
I would like to point out an issue regarding the creation of in-game results and tables considering the single-year based leagues (i.e. Belarusian, Swedish and Iceland ones). The game simply won't add results from previous seasons, even if the start date is postponed to 2024, for example. There are no past winners, too. The last ones that appear are from 2019 (or 2020 in Iceland). Is this a known bug happening in all FMs, since I have found some sources to state that some leagues indeed start simulating in 2021, but it doesn't make much sense not to continue onto the next season, which is 2022, and so on; or that might be a problem regarding just the latest FM game?

I'm running FM 21.2.2 on a PC.

Thank you in advance.

Think you'd be better off asking in the SIgames forums mate

I have also pitched the issue there, thank you anyway.
