Hi Vanessa
It might be to do with where the nodes are places along the strokes in the SVG, or how many they are.
Here is an instant answer on making your own images
Can we take a look at one of the SVGs to advise?
If they're sensitive images you can open a Support Question so they're not public but if you put them here others might be able to help too.

I have an issue with animating the svgs i create in illustrator. The animation does not seem to be smooth like the default images.
What am i doing wrong please?
