Does anyone have problems with leaking sites?

I've been using the AutoSoft infusion sites with my Tandem t:Slim and it seems like every single one starts leaking insulin and makes my sugar skyrocket and forces me to change sites sooner than needed. Does anyone else have this problem or is it just me? It doesn't seem to matter where I put it, it always leaks. I used the MiniMed Quick-Set before for almost 10 years with no issues. Any suggestions or helpful tips? TIA
