Missing postprocess and sync menu entries emoncms 9.9.9

Hi,
after years of successful logging of my data at emoncms.org I looked into logging locally for the future.
I managed to install the latest emonSD-30Oct18 on my old and trusty Raspberry Pi Model B Rev 2.0.
Everything is running fine. Now I would like to merge the 3.5 years worth of logged data on emoncms.org onto my local emoncms server but I unfortunately can’t get the sync tab to appear under settings.

See attached screenshot; everything appears correct and the module is installed; just not showing up.

Any idea where I can start to iron out this issue?

Thanks,

Antonius
