Differential pairs not matching length or spacing

I'm using the differential pairs, and have setup the rules using the Rules Wizard for spacing and width.
They seem to work sort of, but then when you check the length they are not matched. This for example is almost 1mm out.

You may need to do the length adjustments by yourself.
BTW:
- I am not really sure what kind of VIAs you use in your design - double check with you PCB manufacture if they can manufacture it.
- I wouldn't route PCIE signal between pads of the AC decoupling capacitor.

The differential routing just doesnt line match at all, it simply tries to run them by the rule I guess and if it cant it routes it normally.
So I did diff routing, then length matched the signals afterwards.
