Vector (SVG) upload only sees 1 color

I have an SVG with 3 layers, 3 colors.
Howerver when I upload, only 1 color is recognised.
I’ve checked through and again and again.
Anyone know what I could be doing wrong?

Hi @User_EU-3de77027,

please send an e-mail with the design ID to partner@spreadshirt.net.

My colleagues can check what exactly the issue is.

Thank you.

Best regards,
Sandra
