FC25 KEYBOARD PROBLEMS

I bought FC 25 on sale. Since I didn't have my original controller, I wanted to play with the keyboard, but I ran into the following problem:

I set the keyboard settings to keyboard only from the main menu, and when I enter the game, I set it to keyboard only. But no matter what I do, the settings get corrupted when I enter the match, automatically selecting the keyboard + mouse option. I keep correcting them, even while I'm in the match. The match ends, and I reset it again in both places before starting a new match, but it doesn't work. The settings are always stuck at keyboard + mouse.

I need your help with this issue; I need your opinions. Good day.
