Increasing value on post save if different number format

Hello,

First of all, thanks for this useful plugin!

I’m facing a behavior: when I choose the number format different for the default (1 337.55), every time I save/update the post, the value on the field automatically increases.

For example: I choose format 1.337,50 on the ACF field group config.
Then I go to the post using the custom fields, and enter value 20.000,00 on the field. When I save the post, the value on the field increases to 2.000.000,00. If I save the post again, value goes to 200.000.000,00 and so on.

Any ideias?

Thanks
