Annoying or vexing (7)
I believe the answer is:
irksome
I believe this is a double definition.
'annoying' is the first definition.
(I've seen this before)
'vexing' is the second definition.
(I've seen this before)
(Other definitions for irksome that I've seen before include "Troublesome, vexing" , "Annoying - tedious" , "Burdensome and tedious" , "bugging" , "Tediously annoying" .)
