Hi @ido1,
Welcome to the :qiime2: forum!
Do you mind sharing your shannon_vector.qza and Testmetadata.tsv files for me to examine? DM is fine if you'd prefer not to share them publicly. Thanks! 
shannon_vector.qza (52.5 KB)
Testmetadata.tsv (299 Bytes)
Hey @ido1 it seems as if your sampling depth is too deep, it only retains 2 samples; 98039 & W190020. I would suggest looking at your interactive feature table to determine a more appropriate sampling depth to retain more samples.
Check out this youtube video to help determine a sampling depth.
