In InDesign CC 2018, cep extension is not getting displayed in windows menu option, after updating CEP version to 8.0 in manifest file.

Hello,

We are having a extension which is working fine in InDesign CC 2017, now we are trying to use the same with InDesing CC 2018 with supported CEP version 8.0. For that we have updated our manifest file entry as:

<ExecutionEnvironment>

        <HostList>

            <Host Name="IDSN" Version=["13.1", "13.9"]/>

        </HostList>

        <LocaleList>

            <Locale Code="All"/>

        </LocaleList>

        <RequiredRuntimeList>

            <RequiredRuntime Name="CSXS" Version="8.0"/>

        </RequiredRuntimeList>

    </ExecutionEnvironment>

But we are unable to see the extension in InDesign's option "Window > Extensions menu".

Also, If we will keep the CEP version to 7.0 then it seems to work.
