Not able to delete Analytics extension

Hello everyone,

i am trying to delete the Analytics extension from my composer. While following these steps, i cant delete the ThingWorx_Analytics_Builder_Extension because "the following Extension entities are still in use: AnalyticsServerFiltersInstance".

Examining this entity i found out it depends on the TW_ML_Helper Thing and thus can't be deleted. So tried to delete the TW_ML_Helpter thing, but this can't be deleted because it is an extension Entity. Also Its services which remove the filters do not remove the AnalyticsServerFiltersInstance.

When i try to forcibly remove the extensions via the ThingworxStorage/extensions folder, these folderes get recreated once i restard tomcat.

Any ideas how to solve this?

Kind Regards,

Dominik
