Type 90 "Fuji" not getting spalled after being shot

In recent matches when I face Japan and seen some people having the new premium type 90 “fuji” . After being shot to the turret , even though when I would pen them with my Swedish Strv 121 , 0 spall was created and in return , I was the one dying from the enemy .

At first I thought I was being a bad player , bad shooting etc . Until Zenturion7 , YouTuber and now affiliate with Gaijin for WT , uploaded this gem a hour ago showcasing the thing I saw myself too . In the end I wasn’t hallucinating . I hope someone reports this bug . And I hope this was indeed a mistake from Gaijin and some premium bias bs . https://www.youtube.com/watch?v=fPsqL5T5cOc
