Asunto: How many substitutions in league games are there?

A couple of games ago by accident, I was able to perform 4 substitutions in a league game

So I've decided to take advantage of it in my last league game.
I've set up:
- One substitution on 45th minute that happens always (Laktionov instead of Zhenilenko)
- Two substitutions on 45th minute in case I'm winning by a margin of 4 goals (Godulyan instead of Colunga and Bondarenko instead of Sabato)
- One substitution on 70th minute (Baglay instead of Bonsema)
When I looked at the match report I was confused

By the end of 1st half, I was winning exactly by a margin of 4 goals so Laktionov and Godualyan substitutions worked. But Bondarenko substitution has never happened.
However, if only 3 substitutions were available (which was not the case in a game prior) I would expect all substitutions on 45th minute occur, but substitution on 70th minute never happen.
Today I've double-checked my recent match orders and I've made no mistake: everything is just as I've described.
So what am I missing here? Is this a bug or some subtle change in rules?

we have 5 substitutions per game, rules were not updated

Thanks
Seems like the substitution that didn't happen is a bug then :(

Sometimes we make some errors when we set those orders. Once You'll load match settings from that match (by selecting in any senior team that match as an base) You'll find what it was :)

I did exactly as you told me before I created the topic to make sure I made no mistakes.
But eventually, I figured out what was the problem. Turned out that the player who I wanted to substitute was sent off at 13th minute. And that was a reason why substitution didn't work.
Anyways thank you for your help :)
