The "Remove apps" is a generic name for all uninstalled apps. Those 196MB are the amount, all those (uninstalled) apps used when they were installed.
Ex.: If you had Google Chrome and Youtube app installed and they transferred let's say 30MB and respectively 65MB, after you uninstall them, under Data Usage you will see: Remove apps 95MB.
You're welcome.
I believe after 29/May you might have re-installed one of the previous (uninstalled) apps, and that traffic (74MB) is now shown next to the specific app. Otherwise, I can't see any reasonable explanation.
Ex.: Before 29/May Google Chrome was uninstalled after it had used 74MB. After 29/May you re-installed it, and now its traffic is shown separately: Google Chrome 74MB (or more, if you used it afterwards).
