Loading datafiles with UFL does not trigger exception and compression.

I have recently gotten my hands on UFL and are trying to use it to fill in some missing data. It is going reasonably well after I got the correct decimal delimiter in my data. However, I have noticed that exception and compression is not applied to data, and I am wondering if I am doing something wrong as I would expect it to be applied.

I dont have any of the checkboxes ticked to skip the snapshot:


UFL interface, UFL tab.png
The point is configured to have exception and compression:

But a value of 0 is still saved each minute, same as the raw data:

it is normally working:

Are the anyone what have an idea of what I am doing wrong?
