Privacy Advisor shows an uninstalled app that has a lot of network traffic

Hi,
any ideas why the Privacy Advisor - Read Identity Info -panel shows an uninstalled app?

When I click it, the info says:
“Error loading app details
v-unknown, com.blu.javascripttutorial”

Clicking System Info does not work and according to System Resources the app has not been running but it still has quite a lot of traffic at least according to the Network Meter. (6.5 MiB & 86MiB today)
It seems though that the amount of traffic increases every time I use any app that connects to the internet.

thats strange. it seems it was already removed by Google from Play Store as well. can you try adb to uninstall it? do you know how to handle ADB?
