issue with filtering tables

[lucsfar1a]

Hello, 

I'm having a issue about the using of filter in Bi dashboard. I created a table showing some values (april and may) and then I created a Month filter by this table and some others, but this table in particular is not working. When I set up May, it keeps showing me both april and may values. I started to use BI just two weeks ago and I still learning, can anyone help me on this?

Do some free youtube online training about power BI star schemas and data modelling.

Dont just import the data as it is stored on the source tables

Dont use circulare references, many to many relationships and bi-directional filters.
