Hi @MushMan19 the code looks mostly correct, we will be testing and merging the PR,
Few suggestions:

1. It's always good practice to properly description which files you have changes, how you have tested in the PR description.
2. You should bound your code changes to just what it is going to solve, like in your PR you have added the code which will be working for all the 3 issues we have discussed. It's good, but in general not preferred.
