As John says, could be that, but as you need to take the seats and gearbox /propshaft cover off to investigate its worth replacing the 'rubber' bushes while you are there, its not a technically difficult job just a bit invasive and not something you want to do again so replace the bushes anyway, these are polyurethane and wont perish

My bushes failure was extreme and caused the remote to drop and I had to hold it up to get home I was unable to select any gear but third.
You might want to check if the remote has any up and down play by lifting the gear knob.
