Issues with Adding More Than 50 Slack Channels to Dust Workspace

Hello! We've connected Slack to our Dust Workspace. It looks like it's syncing correctly. When I go to add Connected Data to my Company Data (+ Add data from Slack), I only see the channels till the letter B. (I haven't counted them but I would say it's about 50 channels). I don't have an option to scroll to more channels. We actually have a couple of thousands channels. How can I add those to my Company Data if the UI doesn't allow me to scroll past the first 50-ish channels? I don't want to select all channels in this case.
