White Balance bug in newest ACR with EOS R raw files

Earlier today I was editing some photos, then noticed there was a new version of ACR. I hadn't updated in about a month, don't know what my previous version was. I installed new versions of ACR, LR, and Photoshop. My workflow right now is not to use LR at all, but instead to find my raw files on my computer using bridge, and then use "Open in Camera Raw" to edit my photos.

After the latest update, I immediately noticed that all of my photos are WAYYYYY too yellow when they open up in ACR. They are significantly more yellow than the preview files I see in Bridge, which look exactly how I edited them. By adjusting white balance to be more blue I can make them look correct, so I think the issue is ONLY with white balance and not any other settings. This is only for previously edited files. When I open up an unedited file in ACR, it looks exactly like the preview photo in Bridge.

Another curious thing when I was messing around trying to figure out the bug: When I changed the camera profile to something different, then change it back to it's original setting, the white balance changes.

Example for clarity--- Let's say, before I updated, I edited a photo and gave it a value of 4000k in white balance. After updating I open up the file and it LOOKS as if I gave it a value of 5000k, way more yellow. If I change the camera profile and then change it back, let's say from "vivid" to "standard" and then back to "vivid", it LOOKS like a value of about 4500k. The actual value of 4000k never changes, things just look more or less yellow. You can tell this by using the 'P' hotkey after changing camera profiles and then reverting to the original profile. If the only action is to change camera profiles and then change back to the original profile, you should see no difference when pressing the 'P' key. Or alternately, by pressing undo twice.

I have no idea if this is happening with other cameras' raw files or not. I've only used ACR with the EOS R.
