Hi @emmlemore, we are trying to replicate the issue, can you provide us with the primer sequences are you using to extract your amplicon region? I assume you are combining the UNITE tutorial with this [extract-seq-segments tutorial](https://forum.qiime2.org/t/using-rescripts-extract-seq-segments-to-extract-reference-sequences-without-pcr-primer-pairs/23618)?
