Hi first of all, I love bunpro and in general the user experience is very good and that is the reason I use it over Anki for example.
But I was trying to find 頭, a simple word that I wanted to include it in the deck just for completeness.
It gave me over 2600 results, I had to do use the chrome console to find those entries with 頭 as its only text and then focus one by one until I found the 頭 I was looking for (the simplest N5 one).
Maybe I suggest ordering by how good the text input matches the grammar or word? Then by N level? also, I was not able to find the ~て (Adjectives and Nouns) so something must be breaking somewhere.
Regards.
For context this is how it looks for me:
