GP cost of permanent spells from UM- errors?

[ericthecleric]

The standard costs for permanent spells, per the core rulebook, are as follows:
9th-level___2,500 gp
10th-level___5,000 gp
11th-level___7,500 gp
12th-level___10,000 gp
13th-level___12,500 gp
14th-level___15,000 gp
15th-level___17,500 gp
16th-level___20,000 gp
17th-level___22,500 gp
18th-level___25,000 gp

The other spells that can be made permanent in the UM are in line with the above, however, the following spells have incorrect GP costs or CL requirements:
loathsome veil is listed as CL 10, 7,500 gp
sanctify corpse is listed as CL 9, 500 gp
symbol of healing is listed as CL 10, 10,000 gp
symbol of scrying is listed as CL 13, 10,000 gp
symbol of slowing is listed as CL 11, 10,000 gp

What should the correct CL and gp costs be?

Why do these have to be errors? Why can't they just be exceptions to the standards? (I can't see paying even 2,500 gp for a permanent sanctify corpse. That's half-way to a raise dead.)

Actually, I agree that sanctify corpse should probably be that cheap, but the others might be errors. Best to check, though!

[Remco Sommeling]

The symbol spells are unusual in that they have expensive material components.

loathsome veil is probably an error.
