I do not understand the percentage

Hi all,

Long time lurker and first time poster. I would keep lurking but this hand is driving me crazy.

Could someone explain why the UTG player still has 2.8% in the below situation? I just do not see it.
I play recreational, so i have no access to solvers or anything and would truly appreciate some guidance.

What am i missing?

"edit" it is ok, i see it now. Straight flush is possible.

Thank you very much in advance.
