File Editor Trouble

Hello all, I am sure this is a simple fix, but when I got to add an image or file from my file editor through the ADD PAGES shortcut… when I click on the add image button, and then browse… the file editor pulls up but it will only allow me access to the last folder I opened… the “back” arrow button is not working and so I can not add new files. PLEASE HELP…

I am using a mac computer

yup me too.
