Walking animation doesn´t work fluently

Hii =)


I´ve got a little problem with a walking animation i made.
My problem is that at the end of all frames one frame seems to last longer then all the other. I know that it isn´t like that.

I´ve allready asked all my friends and i also didn´t find an answer in the knowledge Base.
I hope somebody could help me =)



Thanks , Sacyra
