SO is the problem having v2 tags which means i need to remove all v2 tags and just keep v1?

No, the only problem is having incorrect v2 tags but correct V1 tags. If you have properly maintained V2 tags, you don't need to get rid of them, they're fine.

The problem only happens when you pour blood/sweat/tears into maintaining V1 tags with a V1-only-capable editor which leaves the V2 tags alone. If you've been using a V2-capable editor all along, then there's no problem.
