Fixed By Weight By Total Configure

This plugin cannot save decimal values.

I am able to set the correct decimal value in the advanced settings. The correct value is shown in the plugin and the shoppingcart is calculating with the correct value. But after editing and saving is 12.5 saved as 125.

Can this be fixed in some way?
Version 4.3

Is the problem in the Fixed entry, or the By Weight By Total pop up dialog?

What is your primary currency? Try entering your decimals with a "," (comma) rather than a "." (period ).

tried both... comma (, )and dot (.)
but both not accepting..

12.5 becomes -> 125
12,5 cannot be entered in the view

So the problem is the ENTERTYPE.NUMBER and DECIMAL doesnt exist...

When entering the value in the Advanced Setting than its working as expected, but when opening it again in the plugin view, than its wrong again after saving...

Currency is EURO
