Lots of #CIRCULARREF inside document

Dear Zoho Sheet Team,

I've imported a document, have been working with it and found it contains lots of #CIRCULARREF error in different rows.

See the screenshot. As you might see there is no any circular reference. If i enter that cell and press Enter this error is gone.

How can i do this for the whole document?

And what was the cause of that error?

P.S. During work with document i saw regular error with your server. Zoho SHeet asked me to save the data and reload the document. What's happenning?
