Stop keyboard down button from turning keyboard into the mini bar

Hi, this is driving me crazy, but is there any way to stop the keyboard down button from making my keyboard into a extremely small bar after I press it? I want to use this button to make the virtual keyboard go away and show up in its full version the next time I click on an input field, not the small bar. I do not have an external keyboard and I'm annoyed eternally for the fact that it doesn't come back automatically as it used to after I press the keyboard down button. Is there no way to tell iPad that, since I don't have an external keyboard, always, ALWAYS show the virtual keyboard in full when I tap on some input field, regardless of how I made the virtual keyboard go away the last time I used it?

I don't have automatic update turned on solely because I don't want this to happen on the device I use for personal purposes (it happened to my work iPad), but somehow it still happened and I'm just on the edge of freaking out because of this. Please help, I am so annoyed at this change, can I reverse it somehow? Just please. It troubles me so much.

update for clarity: I want this in the first screenshot to happen every time I click on an input field, not the second one. I don't have an external keyboard and the second one is just annoying and useless at the same time.
