Important documents are greyed out on Android phone

Hello,

Can someone please assist with all of my important documents being greyed out if i have to upload them somewhere like my sons school for example-i have his immunization records saved, but now i cant upload them because its greyed out and not clickable anymore. All of my stuff is greyed out when I need to upload it, but I am able to attach & send the docs out via email per usual with no issues. Please help me
