New user: retiming error creating AAF from FCPX

Don't worry this isn't critical, that just means that retimed clips will be reinitialized to their normal speed in protools.
But the AAF will be fully functional for your sound editor.

Hi - I am a relative beginner to FCP X. I've edited down a pre-mixed corporate video to a 30" project, and want to send to a sound editor for the final touches.

The sound editor asked for an OMF file, however as I'm working with FCP I can't do that. Instead I've exported as XML from FCP X and used X2Pro to create AAF. (My first time ever using X2Pro!). When finished however it brings up the following retiming error messages:

! Report on Conversion from Final Cut XML to AAF

The FCP X project is 25 fps.

Please could someone give advice, as I have NO idea whether this is a critical warning, or something I can ignore??! I am completely new to X2Pro/creating aaf. Will the AAF work for the sound editor? Thanks in advance.
