Your output viz certainly does look unusual. Developed-under-develop is the only variable that is being pulled, with a size of 1. Does that seem reasonable from your input .qza file? Can you try uploading your bray-curtis_fulldata1.qza file to QIIME 2 View and provide a screenshot of the output viz? This may help us determine where this unusual result is coming from.
Apologies for not clarifying my request a bit further - can you provide a screenshot of the provenance tab after uploading your .qza file to QIIME 2 View?
The bioenv stat doesn't include any plots, which is where part of your confusion may be coming from. More details on bioenv can be found here, for your reference.
