Metahumans and control rig not working properly in sequencer

This is a bit of a weird one. It seems that with the animations I’ve retargeted, when I try to plot these on a control rig using a MALE metahuman, the animations come across with some transforms that are stretching the rig. I’ve made a video below:

When using a FEMALE metahuman, this problem doesn’t exist. In the project illustrated above, all the retargeting was done properly and no female asset was in the project.

Am I doing something wrong? All the tutorials I’ve found on this workflow are using a female metahuman which works perfectly.
