Need help on samples metadata

Hi, for some reason my samples are the wrong way for example I have two lots of samples " bare grass" and " moss" which obviously have unique bar codes attached to them but the sample ids are the wrong way around.

When I submit my data to an open portal i want my metadata to represent what the samples actually are. How can i do this? or can i just submit as it is clearly marking that the samples are what they are. Here is a screenshot:

I know which barcodes are to which samples because i numbered them and made notes as i was applying the barcodes.

Best wishes
