Hi,
Thank you for attaching the sample application.
Apart from some minor namespace issues, we could not observe any issues in the sample and were able to run the same, observing the following output. Could you please take a look and let us know if this is your desired output?
Also, regarding the blank/empty tabs it might be due to lack of space available to render C1RichTextBoxToolbar components. Try increasing the width and it should resolve the empty tabs.
We have modified the sample and uploaded the same for your reference, which can be downloaded from: https://www.dropbox.com/s/mbpu176vrlp4k1z/Editor_modified.zip?dl=0
Regards,
Ruchir Agarwal
