When a standard user (with the “User role”) enters the “Services” → “SLA report” menu and presses the “Select” button next to the “SLA” item (to select a specific SLA), nothing can be selected: the corresponding modal window is nothing does not render.

At the same time, if instead of clicking on the “Select” button, you just start typing something in the “SLA” field, then auto-completion works, and you can select the desired SLA and get a report on it.

I will add that users who are assigned the “Admin role” or “Super admin role” roles do not have such a problem: the “Select” button works fine for them.
