Which browser are you using? This has been happening to some people that use Chrome as there browser. To fix it try the following.
Go to chrome://flags/#disable-slimming-paint
Enable the “Disable slimming paint” option.
Ensure that the “Enable slimming paint” option below it is not turned on.
Relaunch Chrome.
If you are not using Chrome then I would try deactivating all of your plugins and switching to the default Twenty Fifteen theme.
I am using chrome, I Enabled the Disable slimming paint and disabled the Enable slimming paint. I relaunched Chrome, no change disabled all plugins and set Twenty Fifteen as my theme. I’m still getting the same thing.
I looked on IE and everything seems to be fine except my data is still missing.
I set everything back to the way it was, Disable slimming paint and Enable slimming paint. Seems to be working now! Go figure! Thanks for the help.
Awesome! Glad I could help.

Make sure that’s how your chrome flags look.
