Vector files being distorted when uploaded?

Hi, I am having problems with uploading (some) vectors to a project board. The files look okay when they leave affinity, and the thumbnail of the svg is all in place on my mac, but when I upload or drag an drop the file into figma some of the layers get displaced and dont sit in the correct position. Am I missing a step? Other images work fine, just every now and then and it persists with that image, tried resending it, adjusting it…?
