Lost Quote relationship to Line Items

I created a new module which can specify different variables than Line items. I named it “Samband” and established relationship to Quotes, because I want to use the fields in “Samband” when generating PDF´s from quotes. This works just fine.

The problem is that the PDF templates no longer seems to find fields from the Line items module when generating PDF´s. In studio, the two modules “Line items” and “Samband” seems to have identical relationship to the Quotes module, but when generating PDF´s from Quotes, only fields from the “Samband” module shows up in the PDF´s.

Any Idea of what I have done wrong?
