Stupid Question Time

[SenatorCollector]

Looking for some help with a checklist issue. Trying to add a couple Logan Brown OPC Platinum Autographs to my PC, but according to the checklist, he is not in any of the sets. I have the 17-18 Platinum Rainbow Auto, as well as the 17-18 Red Prism numbered 26/50. Any help out there? Would enjoy doing my part to help correct this, AND add a couple more cards to the PC!
Also, while I'm at it, is there any way we can differentiate between our PC, and doubles of items in our PC, we're trying to trade? My numbers are off because, while I may have 4 of a certain card, only 1 is PC, the other 3 are available, but system lists all 4 as PC.
Thanks for the help!

It was inserted in 2018-19 OPC Platinum. It may listed under 2017-18 OPC Platinum Update Set Checklist. At CardboardConnection.com, it is listed on the 2018-19 OPC Platinum page subsection for update.

I pulled the card out of Platinum and it was the only Auto in the box.

I have a couple Colin White Autos from the same set, and they were pulled from 18-19 Platinum, but those are listed in the 17-18 Checklist. Logan Brown is not

@SenatorCollector I just added 7 logan brown autos from 2017-18 platinum, all that were updates in the 18-19 set. Since all of the other updates were already present in these sets im kinda thinking Brown was added to the checklist after I originally entered it. Any other issues just let me know :) Feel free to either pm me or tag me in any posts to get a faster result.
