My Game is using 4.15 and this was a bug that I thought was an issue with my logic as my project relies heavily on mouse inputs and mouse click Combinations. I Ripped apart most of my logic to figure out where I messed up and after I stopped second guessing myself I decided to do a search and found this post. That will teach me lol. Once I realized it was a bug with UE4 thanks to this post I set to find a workaround. I think it was already mentioned here but I found out that just removing the Input mode nodes on my project the bug stopped and the lack of the nodes had no effect on my projects performance at all.
Attached A Screenshot for those who need a visual for this solution.
