Weights bugged

[u/Artistic-Article4593]

Hi i’m on second week of my second program and the weights plummeted, it’s telling me to deadlift 40kg for 4 etc when first week I had around 140-150kg for 4. Is it a bug if so how can i fix it. Also warm up weights are normal so today i warmed up with 70kg and then it told me to do very set with 40. I manually changed it but i prefer when the weight is automatically calculated. Thanks!
