Just to give you some feedback that might be useful for others later on.
Going through "Report issue on this page ...", I was asked to disable particular filters apparently conflicting with what was in the Peter Lowe's list subscription filter. I agreed and it disabled some filters on this Peter Lowe's list subscription filter but also on my custom filters related to taboola by unticking the following custom filter that I had: ||taboola.com^ .
I assume that this custom filter was conflicting with the filters that were in Peter Lowe's list subscription filter.
