I disabled load for a few of them by right-clicking the query name.
Now I changed my mind and want to turn it back on, but it will not allow me. I try to right-click and choose "Enable Load" from the menu, but then it warns me that disabling it will break my visuals. I am not trying to disable it, I'm trying to re-enable it.
I found a workaround: If I duplicate the query, the new one that appears is also disabled but I can enable that one.
