Urgent help: PowerBI

I Created scatter plot with 16 grids using percentile lines (25th, 50th, 75th & 100th). Month filter is not responding to the calculated column SelectGRID & Scatter plot. The requirement is month wise client wants to see each 16 grids data in the scatter plot. Lets say if client clicks on month july then scatter plot will show july month services with 16 grids & now client wants to check each grid wise services. This is where I am facing the issue. Consider the second scatter plot. If july month is selected then in the selectgrid slicer some grids are missing but in the scatter plot all 16 grids are showing. On the entire data the selectGRID & Scatter plot is working properly

DAX used in this I have mentioned in the pbix file
