Classifier error

I have modified my fungal reference database by adding my desired organism( Pythium species) sequence. Futher, I changed respective taxonomy file also by adding taxonomy details for my desired organism.
I got error in feature-classifier when I ran the following command:
qiime feature-classifier fit-classifier-naive-bayes --i-reference-reads sh_refs_qiime_ver8_dynamic_02.02.2019.fasta.qza --i-reference-taxonomy taxonomy.txt.qza --o-classifier classifier.qzv
Herewith I have attached snapshot of my error and my database file id for your perusal. Kindly let me know how to rectify this error?

It looks like many of the sequences you added (but not all) have the ID and sequence on the same line.
