Cannot summon Sea Serpent

[Daluu]

Is anybody getting a problem where it says:

"You are already summoned a monster, The Amethyst Sea Serpent, or the timer has not run out on the previous monster you have summoned, try again in 9 hour(s) Go to the Monster Battle Page to engage your summoned bosses and monster."

My previous monster was killed about a week ago. Still it won't let me summon for some reason.

I have gotten the same problem, and when I go to the monster page I see that my serpent that I summoned before is still there and preventing me from summoning another one.

When looking for a solution to the problem in the forums all I find is to wait for awhile and it will clear itself out. I have waited almost a week and still nothing, not even an x at the top corner of the box.
