If you delete a map while it is marked to be cooked in a custom profile, then run the custom profile the map won't be deleted from the profile .ulps.
I wasn't able to launch using the new custom profile. It threw an error when it couldn't find TestMap2.
Add maps to content with exactly same names, then open Project Launcher's custom profile, unselect these maps and then delete maps from content.
Navigate to <Engine Version>/Engine/Programs/UnrealFrontend/Profiles directory, open profile configuration in text editor and manually delete map entries.

1. Create a blank project. Create 3 maps named TestMap1, TestMap2, and TestMap3. Make sure to have TestMap3 open.
2. Open the Project Launcher and create a new custom profile that has all three maps marked for cooking.
3. Return to the content browser and delete TestMap2.
4. Run the custom profile.
Result: A warning will appear about TestMap2 not being found and cook fails.
Expected: The cook works without any issues.
