The line is visible because after you masked out the frame you applied various color corrections that most likely corrupted your edges. Look for the pre/postmultiply checkbox in - at least - your color corrector.
I am not sure if those options are available in the HueCurves tools though.
If they are not then you have to use Alpha Divide and Multiply nodes to make sure the edges get treated correctly.

An alternative way to go about this is do the masking *after* the grading.

yuhuu! thankyou alpha divided was the solution in this case, place it almost at the end of the output, after trying in several positions, it was solved almost at the end of the nodes, just before a blur
yuhuu! gracias el alpha divide fue la solucion en este caso,
despues de intentar en varias posiciones, se soluciono casi al final de los nodos, justo antes de un blur

Also, one rectangle mask may have been sufficient if you used the invert on it.
