Flag Icon Keeps showing up after removed

I have gone to Menu-View-Columns and removed “Flag” from the Columns so that I can quickly click on the orange dot to “Mark As Read” but every time I refresh it returns the Flag. I do NOT want the flat to ever show up, I don’t need that feature. I only want to be able to quickly mark as read.

Also, the small Mark as Red orange dot is very specific about where to click on it. Many times I have to click several times to get it to mark as red. The sot should be larger or a different icon to click on more similar to Outlook or Gmail icons for mark as read. Quick, easy, no issues.
