LayoutOrder and UIGridLayout does not seem to work with 2-digit numbers

I’m making a shop system for my simulator game (which is already done).
I am adding 15 items to buy, starting at 1 then going to 15.
But, when I change the LayoutOrder, it does not seem to work with 2 digit numbers?

Here is my UIGridLayout:

1st item starts with order 1, 15th item has 15.

Thanks for reading and help would be appreciated! Thanks :slightly_smiling_face:

Fixed. Looks like my intvalue didn’t save.
