League One - Still 23 teams?

So i am playing as Tonbridge Angels (starting from the bottom!)....luckily got through to the 1st round of the FA Cup (20/21 season, this is the important bit), only not to have been drawn!!

Obviously in 19/20 a team gets a bye because of Bury (RIP) but it happens the year after too?! Figured i would do a bit of snooping about and League 1 still only has 23 teams? I thought that this would revert back to 24 the next season with more promotions from Non League etc to make up the full compliment of teams?

Is League One forever going to be 23 teams in FM20? Should this have reverted?

I am not playing any special database with lower levels etc either.

ps. Before anybody asks i did definitely win my 4th round qualifying fixture haha 3-2 v Woking!
