So if i pull to one side i get destortion in another aprt.

You can use a brush mask, and apply the defringe locally.
I often prefer this method, since globally applied defringe can cause color spill in other parts of the image.
It can of course be a lot of work, depending on the image.

I take it you have checked the box for auto correcting Chromatic Aberration? (in the Lens Corrections / Profile panel)
Your screenshot looks more like lateral CA to me - which is what that checkbox addresses. This characteristially varies around the image, but always shifting different hues by varying amounts, working radially from the image's centre in a systematic way.
That's by contrast with the symptoms of longitudinal CA or of overspill 'bloom' - which the fringing controls are there to address. and which can show up anywhere in the image.
