Problems with my game UFC 4

Hello, I have problems with my game UFC 4, my players, online mode, dont cause significant damage to others, others cause a lot of damage to me, including with low hits, hits that dont count, grappling work bad, for example, I have more stamina but cant scape, cant make a submission...etc. a lot of times in Championship, I have to fight with more superior divisions, etc. A lot of problems more...Someone with same problem? Any solution please? Im not bad player and know the game a litle bit,  I have all actualized,  my ps5 is new, game new, etc. ,restaured data, restaured permissions...all. anything works. Help please, is my favourite game!! Thanks.
