Hey,
There's 2 possible problems you could be having,
One is that the cc you have downloaded is only for a specific frames, by the creator,
The other could be that in cas, you can click an option by the pannel that you pick the sims gender, age, voice etc, theres an extra button, and in there theres an option to allow your sims' outfit catalog to be for one, or both frames, or you can just click the "x" at the top of the outfit catalog to disable both.
However, some of the clothing for either frames is annoyingly just allowed for sims of that gender im afraid.
Hope this helped <3
As said, I deleted the CC so that's not the issue, but some of the items missing are ones that I've used on male frames before - it actually shows in the save game of that Sim on the picture, but when it loads, the Sim only shows in their underwear and heels as it was a dress (same for their swimwear as they were in a one-piece).
