ea82 d/r gears moving out of place?

[Subinoobi]

So lately I've been having this random issue where I'll be driving and then my gears move out of place. I can still find my gears and it drives just fine, but where 1st gear normally is it will move where 3rd gear is. like every gear moves to the right, and where first and second are is neutral. after a little bit of playing around it will go back to normal, but this is an issue I should probably look into. Anyone have any ideas what's going? I replaced the bushing on my shifter thinking it was that but it did it again, so that was not the issue. Any help is appreciated!
