Data link for org chart

Is it possible to talk to a tech so I can better understand how Lucid/google work?   I hit data linking  on the left side and notice that the tabs have a number in parenthesis (2) etc. but I'm not sure what that means.  Could this be the reason I'm having issues?  

Hi Dianne thanks for your response and that screenshot. I'm glad to hear that data linking is working as expected for you and you're seeing changes sync between your data and diagram. The numbers in parentheses like "(2)" indicate multiple datasets/tabs by the same name that you've uploaded. If you've uploaded the same tab more than once they'd be named this way within Lucidchart. However without seeing your specific document it's difficult to understand the sequence of events and what you've experienced. It looks like you've opened a support ticket with our team - we'll continue the conversation there so we can take a closer look at what you're experiencing. Please refer to that email for further communication! Thanks for your help and patience.
