Filter in Confluence creates me a double line

Question

I work with the customized field "label", e.g. in the column "Trafo" ( and in other fields I use "label" too).
But only in "Trafo", the Filter in Confluence creates me a double line.

When I remove "Trafo" I have only "one line"

Have someone an idea to fix this?

@Tobias Peter Is it possible there are 2 values (labels?) associated with the Trafo column? It could be adding each value in a separate line of text in the row.
