Is it really the same issue in the post that was linked before? Because if you have the settings as shown by @Meta-Chuh, you do not have the same issue. I believe it is really the new feature in v8.4.7 that was trying to save you from lost data, as discussed in this more recent discussion. If it’s really the latter (and since you say v8.4.7, I am quite confident that’s the culprit), then you will see by reading to the end of that recent discussion that the next version (presumably v8.4.8) will contain a better solution for the problem that v8.4.7 was trying to solve. (And while waiting for v8.4.8, you could re-install v8.4.6, which will go back to older behavior in the meantime.)
