First gear is hard to find new trans installed professionally

[Darthvader-st]

My first fear is in-between where it should be slightly right if it’s original catch point and reverse is lil harder then usual to go into pops out but stays in reverse is it the lockout attached to the gaiter or is it the assembly or is it a linkage
⬇️ this is where first is in between
Example R1-3-5 in between 1-3
2-4-6
