I use command+space as my hotkey and the suggestion in the 2nd link seems to have helped. Thanks.

• What you were doing when the issue happened

I pressed the Alfred Hotkey to bring up the search window and typed 'a', 'p' for one of my keywords. The 'a' character went to the application I was using before pressing the hotkey and the 'p' appeared in the search window. 

• Whether you were able to replicate it a second time by performing the same action

Yes, if 'a' is pressed quickly enough after hitting the hotkey.

• Include any screenshots that might help us
• Include the Alfred version & build number you are using

4.0.2 [1088]

• Include your OS X version

10.14.5
