Export Addon - No string to copy and paste

Mr Robot isnt ackownledging changes in my gear and the ingame addon doesnt have a string in export to copy and paste

The only way the export box would be blank is if you are getting an error. Does an error message show up? Also, what version of the addon are you using?

There are two small addons you can get that help with capturing errors if you are not seeing an error message. They are called BugGrabber and BugSack, both of which are available via curse/twitch app. If you install those, it should capture any addon error messages, and then you can post it here for us to troubleshoot.
