Unable to buy item from store using coins

[linkinblue]

Hi, I am currently having 23.2 coins in my collection but I am unable to buy the Charred Twilight Scale somehow. It's displaying that I don't have sufficient coins. I need help here. Please comply.

Coins are not points and points are not coins.
On your account page it says:
coins: x
points: y
I really dont think you can even have decimal point in coins, they're always round.
