Many unclassified taxa

I was using the classifier pre-trained by Sir Mehrbod_Estaki at Available: Pre-trained classifier of V3-V4 (341F, 805R) region with gg_99. So, I think my targeting region is correct.
I share my taxonomy classification result for the clearer picture. gg-rel-class.tsv (14.7 KB)
gg-rel-order.tsv (28.8 KB)
gg-rel-family.tsv (48.6 KB)
gg-rel-genus.tsv (76.4 KB). There're numerous unranked taxa starting from class level to genus level.

Apart from that, I have doubts about the greengenes naming as shown in the enclosed pic below. What do TM7, TM6, BH180-139,OD1, GN02 stand? How about the phyla name with bracket (e.g: [Thermi] ) ? Should I filter those numeric names for publication?
