I got a disease from killing some skeevers and I went to Whiterun to the Talos shrine. I activated which cured myself. I looked in active effects just to see a fortify shouting effect like this:
The effect says, "Time between shouts is reduced 0%". Is this a glitch? Is it preventing me from fortifying shouts? Only the Amulet of Talos has 20% Fortify Shouting.

Per the UESPWiki's entry on blessings:
The blessing reduces time between shouts by 20%. The value is stored as a decimal (0.2) but rather than converting it to a percent for display purposes, it just reads the decimal value and truncates everything after the decimal place, resulting in the game showing 0%.
This display error is fixed in the Unofficial Skyrim Patch.
