Issue with newer figures in existing Defender Cases

When AEW Unmatched Series 8 was released, I remember seeing someone on Facebook saying they couldn't get the figures in that wave to fit in RSC's AEW Defender Cases, saying the boxes with that wave were not the same as previous waves. I ordered CM Punk from that wave directly from RSC with a Defender Case before I saw that post. When I received it, I checked it right away to see how the figure fit in the case I ordered with it, and it fits perfectly fine just like all other figures I've put in those same cases. I have even placed multiple orders of just cases and never had an issue with them. By the time I wanted the Penta figure from the same wave, it was sold out on RSC, so, I bought it elsewhere. And that's the first time I saw what that person must have experienced. My most recent order of cases was to fit this figure, as well as the Britt Baker Target figure, and others. I had no issues fitting the Samoa Joe Target figure in a Defender Case. But the Penta and Britt Baker figure boxes seem to be shaped a bit different from previous packages. RSC was gracious enough to replace the cases I had that did not fit these figures in case I may have received cases with some defects. But the replacement cases had the exact same issues, so, it's definitely not an issue with RSC's cases. I'm wondering if anyone else has experienced this same issue. Additionally, I've been told the Jeff Hardy Unmatched 9 figure fits perfectly in the Defender Case. But the one I found at a Walmart, same issue.
