Wow, did some looking around and I opposite problems with Secondary roles

I see a lot of discussions here about only getting secondary and such. Now maybe its just me but I practically NEVER get my secondary. I either get my primary or get autofilled to support. Now I used to main support so it hasn't really dawned on me until now because I never minded getting autofilled into that role, in fact it feels like what it should when you put support as ur secondary, which is something I could never do because I would always just get support.

However recently I've kind of picked up a new role (mainly for a specific champion) and put my previous primary as my secondary. What I've realised because of that is that I NEVER get my secondary role. I really wonder what's going on there.
