New warning after upgrading to v6

[siulca]

Just recently upgraded to mobx v6, these are the current packages:

"mobx": "6.9.0",
"mobx-persist": "0.4.1",
"mobx-react": "7.6.0",

And now I get a couple of new warnings, which actually cause the page not rendering at all.

This...

The provided component class (TableComponent)
                has already been declared as an observer component.

... followed by:

The reactive render of an observer class component (TableComponent)
                was overridden after MobX attached. This may result in a memory leak if the
                overridden reactive render was not properly disposed. 

This is how the HOC TableComponent is wrapped in an observer:

export default withTranslation()(
  withStyles(styles)(withStores("authStore")(observer(TableComponent)))
) as <T extends Idable>(props: ExternalProps<T>) => any;

I don't quite understand what change is required as the TableComponent worked fine before. And I can't find any relevant answers out there. Any tips on how to resolve these would be highly appreciated.
