My self-drawn Christmas set was rejected for IP infringement — why?

Hello,
I am a new contributor who just started on Adobe Stock.
I submitted a Christmas illustration set, but it was rejected for Intellectual Property (IP) infringement.
All of these illustrations were completely drawn by myself, and they were accepted on other stock platforms without issues.

I have a few questions:
1) When I search for "Christmas set" on Adobe Stock, I see many similar illustrations with Santa, reindeer, and snowmen. Why would my content be considered an IP violation while those are accepted?
2) Could the issue be related to my title or keywords rather than the artwork itself? For example, using keywords like Santa Claus or Rudolph.
3) If I only edit the title/keywords and resubmit the same file, could it be approved, or should I modify the artwork first for a safer resubmission?
4) If I resubmit a file previously rejected for IP reasons without changes, does that put my account at risk of suspension?

I may be misunderstanding how the IP policy is applied. I would appreciate clarification from the moderation team or feedback from contributors with similar experiences.
Thank you.
