3 on tree / a903

I see that , I have arms off the trans so first /revers arm is floppy but the crossover blade picks up and goes down to 3rd but not second but . But crossover blade will let go of 2/3rd arm but will not pick up the 1st / r arm even with me sitting in engine bay prying on it and someone on car pulling shifter back in neutral I can’t get cross over blade notch to pick up the 1/r nub lol . I have videos of my movement but this site won’t allow to post :(
