Holdout Weapon glitches

[Grahamster]

Hello friends! I am currently facing issue regarding Gomorrah and Holdout weaponry!
I have 100 Sneak Skill, and am attempting to sneak in the weapon Sleepytyme (GRA), the unique 10mm SMG that is silenced
I have finished both "Bye Bye Love" and "How Little We Know" (In favour of Cachino/The Strip)
However, whenever I enter, and click the "keep holdout weapons" option, it still takes all my weapons besides the quest ones (The codac r9000 and Big Mt. Transportalponder)
If anyone has a fix for such an issue, I would be very appreciative.
