Issue with Fleet: Spaces Automatically Removed After Adding and Waiting

Hello,

It seems that Fleet is removing the space after I add it and wait for a second. For example, when I call a function in GO that accepts two parameters, I add one to the call, followed by a comma and then a space. However, when I pause for a few seconds to think, I notice that the space I added gets automatically removed. Is this a bug, or do I need to tweak my settings? I've tried making adjustments, but nothing seems to help.

Thank you!
