PowerPoint File Cannot Modify Bottom of Slide/Footer Cannot Modify/Remove

We have a PPTX file that has a footer with an image and text that does not seem to be able to be modified. I've tried to double-click to edit the visible image/text at the footer but cannot see/edit it.

The file is NOT locked/protected. I've also tried to check the view under View -> Header/Footer as well as the Slide Master to no success.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Would it be possible to upload the file, or one slide of the file for us to investigate this a bit further?

Unfortunately it is confidential so that won't be possible (I know, it's hard to troubleshoot).

Attached is the screenshot though with info block out. Area trying to be modified is in red.
Brian GeeCommented:
Please see if anything changes here...

Try going to View > Header and Footer > uncheck all items that are checked under the Slide tab. Please let me know if the bottom section (in red) is still showing.

In addition, be sure to check the individual slide layouts, not just the slide master. (Or check the slide master -- the big thumbnail, if that's not what you checked before.)

You can turn off the footers on the master and the layouts in slide master view by going to the Slide Master tab and checking/unchecking Footers.

Here's a little info on what's a master and what's a layout: http://www.echosvoice.com/2007/editinglayouts.htm

Header/Footer options are all unchecked (still showing).

Slide Master has the bottom part there but is also "locked" in that I cannot select and/or remove/edit it. Footers in the Slide Master is already unchecked.
Brian GeeCommented:
I'm wondering if this is just a text box placement either on every slide or somewhere in the Slide Master...
Brian GeeCommented:
One more thing to please check... let's see if we can change the slide design in order to determine that what is circled in that red box is not printed on the slide design background itself.

It could be part of an image background, I suppose. That would be odd, but it's possible.

However, have you looked at both the master and the individual slide layouts?
