Wikidata Stats Page show huge drop in statement counts since April 2021

Hey, when researching the total number of statements contained in Wikidata, I discovered your stats page. I noticed that from 2021-02-12 to 2021-04-28 the total number of statements drops from 1.2 billion to 900k (refer to attached screenshot). I assume that this should be due to some bug and that it does not reflect the actual state of Wikidata? Thanks for taking a look at that!
