It has tags for graph matchings + shortest paths but that is overkill. Is there a way I can edit the tags?

A tag is not supposed to be "the easiest way to solve a problem", rather it is "a way to solve the problem". (might also have other information about the problem)
Tags some times may be misleading. The rating of a problem is generally a more consistent measure of what the task actually expects you to accomplish.
An 800 rated task tagged with graphs/ dp,etc. is an overkill. But that’s generally not the case if a task is rated 1400 or 1600.
You said almost the same thing as the OP did. So I'm gonna say this again.
An 800 rated task tagged with graphs/dp is not an overkill. Solving an 800 rated task with graphs/dp might be an overkill. But if it is solvable using graphs/dp, it is not misleading.
Tags just show the approach(es) you can take to solve the problem, not just the (subjectively) easiest approach.
