Board Game Arena

I have played a few games and noticed when placing an orange tile in the 3 spot of the middle star for instance. Rather than being able to use any other 2 tiles (eg cream and red) it will only let me use 3 orange (orange & wild colour). Is this a known issue, I assume it's an issue with programming, because this is different to the actual board game (that I own).

When placing tiles on the center star, you still have to follow normal placement rules - each placement can only be paid for by spending up to two colors (the color you’re placing + the current wild).
