Custom Field Funkiness in WordPress 2.5

Has anyone else been having issues with Custom Fields in the latest version of WP? It’s possibly some kind of plugin conflict, but this is the problem:

When I write a post, every single custom field that exists on my site appears in the custom field section, as though all these fields will be included in the post. (e.g., Some posts contain a “Guest Speaker Name” which is entered into a custom field. Let’s say “John” appears on Post 2, “James” appears on post 3, and “ben” appears on post 4 – they are all in the “Guest Speaker Name” field, and they ALL appear at the bottom of the post.)

Now, obviously, I don’t want all of these custom fields to appear at the end of each of my posts.

So far, the only solution I have is this: For some reason, when I save my post, all the custom fields vanish. So, I have to start my post, save my post, then write the custom fields.

I’m running the following plugins (that are in custom fields): RS Event, PodPress.

Is anyone else having this problem?
