transition cross dissolve shows a carry over from previous dissolve

So i edit clips example car / plane / plate / orange / 4 clips. now when I shot the footage, lets say after the car, I get a short 2 secs of the ground. I toss this out of the cut clip. now I add the cross dissolve between the car & plane. cross dissolve works perfect. now when I do the next cross dissolve between the plate & orange, I get a frame of the previous dissolve. the ground

looks like this 10 secs plate, 10 secs orange, add the cross disolve, and get 1 frame out of 30 that has the ground.

Like the transition is corrupted / poisioned by the previous use.

I ran thru every frame of the car clip and the last frame is just the car the "bad" ground footage was cut and deleted. yet it shows on the next edit. dissolve

anyody ever experienced this, or maybe a solution.

thanks for the help
