Hi
Windows 10
Photoshop CC

When I use the Polygonal Lasso tool I have the box chosen "add to selection"
I have been using that to select and select more and when I want to subtract I select the "subtract from selection box"

Now for no reason once I select something the tool automatically switches to subtract from selection. This is driving me crazy for I would repeatedly make numerous selections in a row. Now i make a selection and when I spend all the time adding to my previous selection I find that I am in subtracting from selection mode.

Why did this change and how do I stop this?

Not sure what's going on, but try resetting your tool. If that doesn't work, reset your Ps prefs.

If IamSam's suggestions don't work, another angle to consider are the system settings for sticky keys. If you use a modifier key to switch between add and subtract selection, it will "stick" in the new mode until the modifier key is clicked again. Here is a link about what enables and disables sticky keys in Windows 10. Not sure this is your issue yet I have seen it cause the problem with a few others
