Drop down arrow for folders missing

So this has been happening since El Capitan for me. Seems to be random, and not every folder. My View is set to List, and Arranged as None. The only way to get the arrow to show up, is if I close the window the folder is in, and re-open it. Or open the affected folder, and then hit the back arrow. Essentially refreshing the window.

Anyone know why this is happening? Has there ever been a solution? You'd figure, since El Capitan (and I'm on High Sierra now) Apple would have addressed long standing issues. That's the problem I have with Apple these days, they continue to skip fixing issues that's been plaguing users for years. Across mulitiple OS's.
