The original "sticky" capslock hyperkey problem I mentioned is still a problem in the current release (3.812). In the screencast, I am using ⇪capslock alone to trigger Alfred. I depress and then release ⇪capslock and Alfred is correctly activated. At this point the ⇪capslock key has been fully released.
Then in Alfred I type single keys beq — the b enters into Alfred without issue (I do not have any hyperkey+b bound), but e triggers "Resize to right" ⇧⌃⌥⌘E which is the BTT binding you can see in the screenshot in the OP. To reiterate only e is depressed at the time the ⇧⌃⌥⌘E binding activates!
