Hello,

Please never publish your access data on the forum - due security reasons I have removed it, but you should also change your login and password.

Regarding the problem - if you're using K2 articles as a data source for tabs, then the text comes from the article content. You can set the slide content type to "Text" and then you will be able to put your own content.
