fix: overlapping input label when filter select is outline (#1334)

As stated in the API Documentation of MUI https://mui.com/material-ui/api/select/#props the label should be shrunk when display empty is true.

I do not know why we need the display empty. If we remove it, the error also is removed. So you should consider what the use-case for displayEmpty really is.

Fixes: #1142
