Animate Pie Chart

Hi! I am learning how to create an animated pie chart in Storyline 3. I have created a test with 3 sections of the pie in different colours. I have also animated each section using the wheel. On the first blue section, I noticed when I tested the animation, it looked like it did not start at 0 degrees as it goes back to 'finishing' it and then continues to complete the orange and green sections. Is it because I have not quite lined up the blue section? I have attached the storyline file here. 

Can anyone offer any advice please?

Thank you 🙂
