Android 6.0 is supposed to group widgets by app name. I'm attaching a screenshot.
And so, on 6.0 and newer, our widgets' titles are just "Counters", "Messages", "Text to speech" to avoid the duplicate "Aqua Mail".
Unfortunately Android does not provide a way for us to know if your particular launcher groups widgets by app name (which we assume on 6.0) or if it doesn't (your launcher).
( note how Google Calendar widgets do not have Calendar in their titles either for same reason )
