About Mid-season Break Setting not work correctly

[that\'s play soccer]

As title 

i used a preset league model (like K league 1 or Aus league)
I set "Mid-season break" in Naiton Tag like pic1. Then create a league. but when i used editor test funtion, fixture didn't work corretly.

In pic2, you can find the game played in mid-season break range.
In preset model, It didn't  set break period. Should I set that? (like Pic. 3)

Or i made something wrong?

Make sure to check it in game as well. While the testing function in the editor is useful it might not be doing everything correctly.

I usually use the individual league options for break periods in addition to the overall nation rules. Also, ensure to check the "Block Postponments" option while enabling breaks via league schedules.
