How to interpret "Local Position setpoints" in Flight Review for a VTOL


I am trying to interpret my logs from a few VTOL flights. From the logs, it seems that the UAV follows the desired mission very well. However, by looking at the “local position” plots, there seems to be something wrong with the setpoints. Please see the pictures below:

How should I interpret this? Is this a bug with the log/plot tool, or am I missing something?

Thank you!
