Panthera Prime Riven Disposition Not Updated

[(NSW)Morrigan91]

So apparently according to the patch notes from Nezha Prime's release back in October, the Panthera Prime was supposed to be updated from a riven disposition of 0.5 to a riven disposition of 0.85. And yet, when I look at my panthera prime, it still only has a riven disposition of 0.5

Is this a bug that anyone else can confirm? I've been asking and asking on switch but no one has been able to tell me why this is the case.

Is this the case with all weapon dispos that were updated at Nezha Prime release? There have been several switch patches since then and this issue still has not been updated, its really disincentivizing me to play. I have been waiting since June of 2020 for Panthera prime's riven disposition to be updated and its still at absolute minimum.
