there's probably an option like Internal OSC I/O. And you will need to set MCLR to internal to free your RA5 pin.
Personnally i prefer to do it in the code instead of setting config fuse manually in the programmer software.
Look at the following to know how set the PIC config fuses in your code:

Now, if my memory is good, the F818 default oscillator speed is 32KHZ, have a look to the datasheet in the Oscillator section. Search for the OSCCON register or something like that. Also look at the following link to Melabs Website

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.
