Filtered Calendar Slicer Not Working

Hello,

I have two calendar dates one fore general filters  (by slicer) and another one to select a previous coparation period. I want that the general slicer filters the comparator slicer doing that min date (minus one day) on general slicer would be max date on comparator slicer.

Something like this:

So I created a Measure that indicates that and I filtered the comparator slicer with that measure:

ShowDate =

var  MinSelected = MIN('Calendar'[Date])

var MaxCompare = MAX('Calendar_Comparations'[Date])

return

IF(MinSelected > MaxCompare , 1 , 0)

 

All is working fine until on the comparator slicer I select as max date the min date (minus one day)  of the general one, the filter is not working well:

 

here is working well

 

Not here (when the max date posible is selected)

Why is this happening, what I am doing wrong?

 

Thanks
