Tail not holding Pixhawk

Hi all, I’m having a few issues with getting my tail to hold on a Rex 500. The tail almost seems to be behaving like a rate mode gyro. I’m having issues with my ground station at the moment to retrieve the logs but I was wondering is this could be remedied by tweaking the P values?

There are a lot of values that go into this.

If you can’t get the logs, even just the parameters would help me make a suggestion.
