Custom functions are not properly updated when loading data

[Hugal31]

When loading another data file with the same field names and same timestamp range, without erasing all the plots, the custom functions are not updated property.

The CustomFunction::calculate method is correctly called, but the function never pass the timestamp check here.

I am not sure if this is me misusing the software, or if this is a bug.

Data used for the test:

time,value1,value2
0,3,4
1,5,6
2,0,2
3,-5,0
4,-3,0

plot2.csv

time,value1,value2
0,-3,10
1,-5,-5
2,-0,-3
3,5,-5
4,3,-2
