Xbox Series X-Gatekeeper emblem not calculating points correctly

Step 1 : Boot the game

Step 2 : Play as any killer in a public match (bug encountered with Nemesis, Mastermind, Cannibal and Singularity so far).

Step 3 : Play the game normally (for more certainty of extending the game beyond 9 minutes, which should grant significant points according to the emblem descriptions, use generator slowdown perks such as Pain Resonance and/or Oppression).

Step 4 : After the game, notice how the "Gatekeeper" category has very little to no points, making pipping almost impossible at Gold/Iridescent Grade and very difficult even in lower Grades.

Additional information

• Frequency of the issue: Not 100% reliable, a game ending in a "Merciless Killer" rank seems to be exempt from this bug, forcing a full victory to avoid losing potentially 25% of (the maximum) possible emblem points.
• Slowdown perks used were Pain Resonance and Oppression.
• Picture of Post-Game Emblem attached
• In the game from the image, 2 Survivors died, one of them having purposefully sped up his 2nd hook phase, 2 escaped (both of them were on 2nd hook, one disconnected prior to getting hooked for the first time (not certain if this makes a difference)), the Survivors were quick to heal injuries and often used the basement of the school in Badham Preschool alongside Boil Over to essentially make hooking nigh-impossible and forcing me to either let them downed or have them wiggle out (which made me lose a lot of points in the Malicious Emblem category through them recovering).
• Side-note: wasn't there supposed to be a hook down there if Basement wasn't in the school to prevent this exact situation?
