Lot's of kits /planes have 1 or 2 degrees of right thrust builtin, for the reason mentioned above.
So it's normal. Perhaps this is your first "bigger" plane, where it is more obvious. Also, the bigger the plane, the bigger the engine, the more prop effect you will have, so the right thrust becomes more important as the planes go up in size
(small kits or trainer will not have this right thrust as the prop effect is far less noticable)
