RadzenNumeric bug?

Think Ive found a bug when using radzenNumeric in a datagrid. Quite often when entering a negative value in the input fields and then tab out - the value changes to positive. It seems to happen more often if entering a larger value.

Initially I thought it had to do with the formatting, but the problem occurs even without the formatting.

The problem is reproducible in the demo enviroment:

I've updated several items however didn't get such problem:

I made a screen recording showing the bug.

Maybe its related to cultureInfo settings? We are using both swedish and norwegian and are experiencing the bug with both.
