Missing strings on kodi-core translations

Hi,

I’ve found some missing strings for Kodi 17 on Transifex kodi-core strings. I’ve looked up for them on various languages with no success, but I’m translating SPANISH (ES) language.

on SETTINGS -> LIBRARY SETTINGS -> IMAGE SETTINGS there are two strings:
“Show EXIF picture information”
and his explanation
“If EXIF information exists (date, time, camera used, etc.), it will be displayed.”

on SETTINGS -> LIVE TV & PVR SETTINGS -> PLAYING
“Switch to full screen”
and his explanation
“Switch to full screen display when starting playback of channels and recordings.”

on SETTINGS -> SYSTEM SETTINGS -> POWER SAVING
“Maximum wait time for network”
and his explanation
“Set the maximum time to wait for the network to come up after starting or waking up. When time has passed before network is up startup will continue.”

on “SCREEN->Monitor” options, the DEFAULT value is no translatable too, but I think this is a system value, not kodi value)

All of them must be on kodi-core project, or I suppose it, but i cannot translate them.

And I can’t find some of the “icon tags” on SETTINGS menu (System Settings, GUI Settings, etc)

Thank you in advance
