Had a reply from Xara below;

A workaround will be released in the coming weeks. Apologies for the delay in resolving this. At present all i can recommend is manually removing the tag. Once the next update is released you will be able to resolve this through a workaround in the program. Id recommend contacting us again towards the end of next week and we should have a clearer picture as to when this workaround can be applied.

Anyone know what the tag is?
