Were you sure you had enough points to buy an upgrade???
With the powers, I understand it is difficult to adjust with the cost ... Generally if you have one or more non-colored 1 in the binary number (the small one) you can buy one or more upgrades...
At first I wanted to make the 1 of the binary number coins, and that they could be spent individually, but I didn't do that for lack of time... (Maybe it was for the best, because it's hard to understand)
