Hub adapter problem

[Silvi]

I Bought sparco hub adapter for s14.
When I finished with the installation I checked the signals and they wont stop.
So i tried to figure out where is the problem and I find out that the hub end slips on the signal blue panel:

Here is picture of hub end:

And after I put the back panel back - the hub rubbing the plastic when I turn the wheel.
Someone have a solution for this issue?

Thanks!
