I think you are correct. There is only AMF Mix that is global fixed income fond with SEK hedge.
We have talked about this in another thread. When you invest in global government bonds the yield is quite low. The cost for hedging SEK from USD is quite high. This is an indirect cost in the fund. (FX hedge can cost between -1% to -2% depending on currency).
That’s why I buy a fixed income fund with Swedish government bonds. The yield will most likely be the same or better than a global one with FX hedge.
I am using Storebrand Obligation A. It has Swedish government bonds and with a AA+ rating. 
AMF Räntefond Mix is a great fund and more diversified, but I am not sure if it will benefit you in the end. Compared to a Swedish fixed income fond. Especially regarding government bonds.
