The mask, in your case ?1?1?1?1?1?1?1?1 must be at least the length specified by --increment-max (or longer).
How else would oclHashcat know what it should do after the position @ end of mask
Your mask ?1?1?1?1?1?1?1?1 is of length 8.
But at the same time you specified --increment-max 10 (this can't work!).
How to fix: use a long enought mask, that includes the full range from the length specified by --increment-min and --increment-max
For instance:
-a 3 -1 '?l?u?d!@#$%^&*' -i --increment-min 8 ?1?1?1?1?1?1?1?1?1?1
As you can see here, you can skip the --increment-max in some cases, since maximum mask length (and hence --increment-max) is implied and limited by the mask length itself.
P.S. You say "this command would find all passwords 8-10 characters that matched my custom charset", but this is not true since -t 60 will not "find all", since you apply this particular markov threshold.
