Table showing up underneath side panel

Hi everyone,

I've been developing a dashboard in which I've used bookmarks to create interactive side panel, where I have some filters (slicers) as can be seen below [green arrow pointing to where I click to expand the filter pane].

 
Then when I click, it works and it expands as can be seen below.

 
The expected behaviour is exactly as it shows above, with the table being underneath the pane. However, when I hover the mouse over the table, it kinds of "brings it to the front", even though the table is the last element on the layers, as can be seen below:

 
Has anyone ever had such an issue, and if so, how did you solve it?

Thanks!
