Messed up setting pre-release, now all tags include "true" string

[TheTFo]

I accidentially set prerelease to "true" (with quotes, as a string), and now it seems that all my prereleases for this particular channel are using the format "v1.0.0-true.n". I tried going in and deleting those tags, yet they continue to do increment using "true" instead of the channel name.

What's the best way to fix this? Do I need to delete the branch?

Thanks!
