Cant allocate passive skill points

Level 13 Huntress, I've spent my 1st 2 weapon set passives but now I'm unable to allocate any more passives.

Reloaded the game, no luck.

Unable to allocate my 2nd lot of weapon set passives either.

I have the same issue. In the top right of my passive points, it says I have "Skill Points: 3, I Weapon Set: 0(4), II Weapon Set: 4(4)". I found a Reddit thread were the user was able to fix this by refunding points until the 2 weapon sets matched. This didn't work for me. Instead, I now can't assign 1 point that was previously assigned (not to mention the extra 2 points) and I've lost a bunch of gold. I hope there is a fix soon.
