Measure doesnt change over time

Hello

I have measure where I just divide two fields from two different tables (sum of these), but I can see that the value doesnt change over time (when I slice by using slicer date). I know its kind of static measure because its most likely that entire year it shouldnt change a lot (when it comes to values itself) but the count of lines which needs to be sum changes (i.e there were more items in 06.2022 than 06.2022). 
Any idea how to get it going? I have standard star schema

my measure is

DIVIDE (
SUM (  (Table[Amount]  ), SUM  ( Table2[Amount ) 
) 

I am for a long time in work today maybe I don't think accurate right now
