When adding new Tag it “creates” a bew “branch”

[celsomtrindade]

I'm new using SourceTree (and git/version control in general), so I don't know if this is the expected behavior, but I don't think so.

I have a project with some commits. When I started adding tags to this project I noticed it started to create new "branchs" automatically in some tags. Not all of the tags does this, and it's also not an actual branch, but it displays some different colors, which is making me confused.

See these images below:

After adding tag "0.3.0":

As you can see, it created a new color/line, kind of representanting a new branch in paralalell. I don't know what I may have done that caused this, but I'd like to be able to create new tags and keep only one branch.

Also, depending on the number of tags I add, it can have more lines/colors. At one time I had 6 different colors.

How can I solve this?

Hello! It looks like those are actually 2 different branches (keep in mind that colors are not always the same for each branch). If you look at the commits in the first picture, you can see they're actually the same commits as the pinkish color line in the second picture. Here's a img with the blue line faded out, and the orginal line colored to be pink:

Hopefully that clears it up.

But inside the "Branch" menu I onlye have one, which is "Master". Also, I didn't created any other new brach, the only thing I did was these steps:

Right click > Tag... > Add tag

After confirm to add a new tag, that thing happened, and I don't know why.

I assume there's someone else who works on this project? After adding a tag SourceTree will typically perform a fetch, which will update the Log with other branches other people may have created.

No, I'm the only person using this. The only thing different from commiting I did was to return to a previous commit to undo some changes (Reset current branch to this commit), and then continued using it normally.

This is why I think this is weid.

If you follow the blue branch, what's the newest dot? I suspect you may have created a detached head by returning to a previous commit.

Actually I removed all the tags because it was a really big mess! I had over 6 different colors/lines, it was impossible to follow along with that.

To add on this comment, when I remove all the tags, it stays like the first image, just one "branch"/color and everything in order. Just like it was supposed to be.
