Thank you for reporting the issue.
You're right. We're already discussing how to sort the completion at https://community.devsense.com/d/662-sort-intellisense-options-by-recently-used-first-and-then-most-rellevant .
It's definitely on our to-do list, to push the most relevant items on top of the list.
