Description
the size assistant here fails to calculate the min and max values for a variable. This might be due to a weird field name: 01/08/2015 01:00 (derived from an xls file).
File attached.

I think the issue here is that "01/08/2015" is a string field.
If I use the expression to_real("01/08/2015") in the size assistant then it works correctly.
Can you confirm?

In earlier versions the string field was listed among those usable by Assistant. Now the behaviour is correct.
