In Romans 5:1, the TGNT uses έχωμεν which is Subjunctive, but it is tagged as a Present Active Indicative, which is what is found in UBS 5th, NA28, Scrivener 1881.
The tagging here must be corrected.
Bump
I've filed an issue for this to be reviewed.
There's a similar issue in 1 Thess 2:7
THGNT chooses the variant ἤπιοι rather than νήπιοι (NA28 etc), but it's tagged as the latter.
Thanks, I've added this to the report.
