Logic X Saying Audio files not found

Hi,

Having a bit of trouble regarding opening projects of Logic X. When I open a project it says the file of a different name, untitiled_1#11.aif, can't be found. When I click search the project which I originally clicked opens then a pop up appears which says the same untitled file as mentioned before can't be opened but unsure what this is or why these pop ups are appearing. I've searched my MacBook and can't seem to find this file. My project appears to be okay but just annoying that this is happening every time I open this up.

Is this because Logic is looking the above file mentioned? I did delete other unused work on this project so just wondering if it's related to that or something daft I'm doing wrong.
