Lost several months of data after re-processing


a short introduction: We had to report on a large set of subpages. Here we ran into problems with the default Matomo configuration, which let’s you only see a maximum of pages in a report (the rest are then just accumulated into “Others”).

We then followed https://matomo.org/faq/how-to/faq_54/ to increase this limit and re-processed the data according to the FAQ. This has worked fine.

We have lost data from several months. We have Users, but all ‘Actions’ (including Page Views etc) are lost in that area. See screenshot => https://gyazo.com/6db6431d69649f203653b9b156c285ff

Any explanation what went wrong here, or even how to perhaps restore data, would be greatly appreciated!
