Saved patch won't submit bus sends and aux tracks

Hi!

I'm saving my channels as patches for later import in MainStage, but the aux tracks won't come along. Apple states:

In addition to the features of the channel strip setting you may be familiar with from earlier versions of Logic, patches also save any aux channel sends that are needed to reproduce the complete patch [...] (Logic Pro X: Using and saving patches - Apple Support)

However, when I create an empty project in MS, or Logic Pro X for that matter, the bus sends and accompanying aux tracks are not included. Am I doing something wrong?

Kindly,

Joachim
