I've seen other users with similar issues and the problem was
either a faulty SD card
or
a fake SD card
Not all the apps can be moved to the SD card, that's up to the app developer

try this
settings > apps > all > sort by size > tap on top 10 apps and clear the data/cache > restart the phone > check again
also post a screenshot of
settings > storage
Using file commander app.
