Problems protecting content with categories and more tag

Hi, I'm having a hard time getting Protected Content to function properly:

1. If I protect category X, and add a post ONLY to that specific category, protection works fine.

2. If I protect category X, and add a post to category X and Y (not protected), the content is NOT PROTECTED.

3. The wordpress MORE tag is not protecting the content (I added the membership to "Hide "read more" content" option).

4. The membership shortcode is not protecting the content (I added the membership to "Hide "read more" content" option).

On items 2, 3 and 4, when testing the membership, I get the following: "Allowed by Rule: Categories" (even in items 3 and 4, after removing any memberships from categories).

What should I do?
