Hi, I only have the first of my 2 slots of research visible when going to manage it in the Stronghold. My second research activity was completed, but I could not interact with it to finish or start up a new research.

Did you accepted the results of the finished research? You have to do it to actually put it in effect.

I have exact same issue. Problem was i accidentally spent currency to speed up existing research to be able to access "hidden in the background" complete research. And now ive the same thing again. I took the screenshot. Ive 2 slots researched but only one visible and im not also 120+ something currency short after accidental speedup.

It sucks that this bug cost me actual gems.

Also here's my actual building research ^^

If you believe, it's a bug, try to contact Amazon's support about it. Only they can help you with in-game bugs.

its not that "i believe" its a bug, its that "it is one"... I have logged a ticket and I'll post progress. I dont think I'm the only individual with this issue. So likely theres others.

As per screenshots only one slot is visible, theres notice for completed researched (red dot on the left hand side panel) but its only showing current ongoing research. That's the bug - second slot is hiding behind the forefront one.

Try this, select the "Completed Researches" from the drop down selector, then select the related research from the list and see if you can click something like "Accept" or "Confirm" button in the right part of the screen. If the research is finished, but you didn't actually clicked that button, it doesn't counts as completed and the slot will not be unblocked.

Looks like it was indeed a bug in the game. From yesterday's patch notes:
"Fixed an issue causing the Stronghold Lab UI to not display additional research slots when unlocked."
