bugs by articles creating in Confluence

[Seven Network]

Hey! we are using Confluence 7.15.0 and sometimes we have problem by creating Wiki articles. After we save all changes in an article we can see that the text contains extra spaces and contrarily. How is it possible? We checked permission roles that our managers have, but it didn't help to resolve the issue. Can you help us? Please let me know if you need screenshots. Thank you in advance!

Hi @Seven Network ,

Can you please tell fi you copy/paste text from some other resource? If yes, these can be "invisible/nonprintable" characters that are copied to the page storage format and cause such behavior.
