If this is the last mount point you create, it's made as large as possible by not entering in a size value. Or you can enter a value greater than the value reported as "Available Space" in the magenta box, lower left corner.

Probably because it wasn't a contiguous 14GB. I've not recently (since F18) seen it fail to allocate what you ask for, if it's contiguously available. The "available space" amount shows all unallocated space, including non-contiguous space. So it's possible for that value to be greater than the largest possible size for a regular partition.
That's why for standard partitions, "fill all available space" is a misleading choice and it's best it's gone. Hypothetically, non-contiguous portions could each be made PVs, added to a VG, and then you could make an LV of any size up to the maximum truly available since LVM can use non-continguous extents since it presents them as contiguous to the file system. But in practice, the installer won't actually create such a layout, and that's probably a good idea also because even though it can be done, it's complicated and thwarts the allocation mechanism of the file system, better to just fix the problematic existing layout.
