PC Fighting games with Recroom masters 4 Player controller

[atrain9]

Looking for any help on using my Recroom masters 4 player controller stick (IPAC2) with games such as Injustice 2 , Tekken7 or any other fighting game!  I am not able to map the controls and my recroom masters 4 player controller stick is listed as a keyboard in the games however some buttons will map but a majority of them wont ?? I am able to play Shaolin vs wutang without any problems and the buttons map fine as it lists my 4 player recroom masters controller stick as a keyboard??  Thanks!!
