Bobcat S300 aux hydraulic issue

On my S300, I have one aux hydraulic coil I think is either not turning off or come crud is in it. I thought I would check and see if anyone has had a similar issue.

This came up last year a little bit but found a loose coil and thought that was the end of it. This weekend I was using the grapple attachment on it and when I would raise the grapple it would stay up like it should when I started, but by the end it would stay up as long as I held the paddle switch to the right.

If I let off...
