I think there is some confusion due to the complexity of the Help stuff in Logic.
You have to differentiate the following "levels" of Help
Help Tags
The term "Help Tags" is used for a specific type of window called a "Popover", these are the black windows that have a little arrow, the "Anchor" pointing at the object they providing information for.
These Help Tags can be disabled in the Preferences
Tooltips
The Tooltips were originally little yellow tags, that are now gray that pop up when you move the cursor over an object or area on the window. THey provide short info about that item or area. Recently, these Tooltips also list Key Commands.
Usually, these Tooltips were always on, but in a recent Logic update, they are also disabled with the same Preferences checkbox for the Help Tags.
Quick Help
Quick Help is another "online" help feature, that you toggle with the QuestionMark Button in the Toolbar or from the Help Menu. This information was displayed at the top of the Main Inspector or could be torn off as a floating window.
Now in 10.3.2, has a new command "Quick Help Follows Pointer" in the Help Menu that displays the QuickHelp info as a yellow Popover that follows your mouse cursor. THis is very cool for learning the components (especially complex Instrument Plugins), but it can be annoying during regular operation.
Make sure to disable that feature "QuickHelp Follows Pointer" in the Help Menu or disable the QuickHelp all together that should take care of your "problem".
There are even two more levels of online help: Help Window and Smart Help, that's where the real fun starts. I explain all those details in the workflow chapter of my book "Logic Pro X - The Details".
Hope that helps,
