Containers in Records 1 to 400 get synced, but not afterwards

The containers are filled with images.

Then there are also some records where there is a html text doc in the container.

which might have caused havoc to the es record uuid fields following. 

Some contain html like div tags.

I am almost certain that i did not overwrite the uuid fields by hand.

What could have brought this about?

 Also.  should i abstain from storing text-like html in containers?

Any comment would be much appreciated.
