I have created a trigger with no errors and I have a mutating table, I have never come across this before, what seem to be the issue?

The rows aren’t changed immediately, the changes are made row by row, and after each change your trigger is invoked.
When it’s invoked – it selects from the same table which is semi-changed. This is inconsistent, thus – oracle prevents you from doing that.
You probably may change it to
FOR EACH STATEMENTand process the bunch of rows how you want, or even rethink the task (there is a chance you’re solving it wrong)
