What does a '+1' next to a commit mean

[sal-420]

First, I'm a GitHub and VSCode light weight

I pushed a commit on the main branch, followed by a tag commit. I had to push the commit using the terminal versus VSCode. This resulted in the commit getting a '+1'. I tried to resolve the '+1' by creating and pushing a branch to main. This still did not work.
I cloned the project to another folder, pushed another commit to the main branch. Pushed another tag commit to GitHub using the terminal, the "+1' icon has moved to the new tag commit

2 Questions

1. if this is an issue how can I resolve it, googling has not been helpful
2. Can you point me to the documentation location where the icons and definitions exist
