Shapes rendering incorrectly/distorted

Hi,

I'm having an issue when exporting shapes.

Looking at the below, the top set of shapes are within Premiere Pro, but the bottom set are how they export.

These are standard shapes to demonstrate the outcome of a penalty shootout.

I'm exporting using the 'YouTube 1080p Full HD' preset, and have tried to export within Premiere Pro directly and via Media Encoder, and have tried both 'Renderer' options within Media Encoder.

This is using version 24.0.0 (build 58).

Any ideas?

Thanks!
