Can't get to the submenus on Toolbar by clicking on the little triangle

First, there is a checkbox in Preferences under Tools that says "use Shift key for tool switch" that you want to make sure is checked. You most likely have already done that but I wanted to get that out of the way just in case.

Now, I had an issue where my tool's submenus disappeared one day and all the tools in the submenu's (and others) seemed to to be located separately all in one place at the bottom of the tools bar located inside the tool that looks like this "•••".

I apologize but I can't remember exactly what I did but I was able to change it to the old way, with the normal toolbar with submenus of tools that you can use shift to access. It is possible it was under Edit > Toolbar. I may have just restored defaults or something but at the very bottom of this panel where it says "Show:" make sure, if the 3 dots are selected(•••), that to the right of the icons,  the checkbox, "Disable Shortcuts for Hidden Toolbar Extras" is unchecked.

Right click on them to bring up the sub menaus.

Hi

I am on Windows here, so it may be different on the Mac,  but does click and hold on the tool bring up the alternatives?
