Bug report S1 3.5.1: Instrument FX Chains are stored as Audio Track

I've made a great, flexible VI bass preset using Presence, plugins and my NI KK S61 as controller. But I can't seem to store it properly (in the right format) in S1: When I do (from the Inserts menu in the mixer) it then loads as an Audio chael instead of an instrument chael. I've tried it in both 3.5.0 and 3.5.1 to the same result. That's not supposed to happen right? If so this is a bug report.

If I missed something please tell me.

I'd also like to thank you so very much for the 3.5 update. Amazing work. You guys are simply the best!
