Ubuntu 20.04 Unable to locate directory

I am trying to configure SR on Ubuntu 20.04. However, I cannot add root directories nor can SR locate the download directory for post processing. I will try to explain what is going on.
In General Settings, I clicked on Add under “Show root directories.” It brings up the box to choose the directory or enter it manually. If I enter it manually and click ok, nothing shows up in the box. If I try to search for the directory, it just repeats the same set of directories when I click to open one. (I really don’t know how to explain what it’s doing here.) The same thing happens in the post processing section.
I’ve tried searching the forum as well as Google, but can’t find anything similar. TIA!

Are you running SR with root permissions or does SR have permissions to the folders you are trying to use ?
