No Plot showing, only one Tab.

Hello,

I have an issue with my Bokeh app, Can someone help me out.

This error as seen in above appears.

Since am developing on my local machine.

I expect to have a plot with three tabs, however only one tab seems to be active(the background fill).

With othe tabs, no background fill appear when selected

with jupyter this is what appears

which is what i expect but with some WARNING

So i wonder what is wrong with my code.

Please you kind support will be appreciated.
