Seal card problem.. Please help

Im not able to use seal card in veteran or expert mode...Idk if its just me but it seems like it... From what I've been reading in other post is that people can capture monsters in the veteran/expert mode.. When I go into any battle in those two modes the only options I have is to switch monsters or simply fight back... Someone please confirm if my game has a problem or I'm just reading these other post wrong.

I read in a recent post that u can seal Neo in a veteran lvl in Volcano... When I get to that lvl in veteran I'm gonna be really upset that only I cannot seal him (for my second time) (already have him) lol

You can only catch monsters that can be found in caves. By caves I mean caves.

Can anyone upload a pic of a "cave" please I'm very confused on what the "cave" is... I've been playing this game for over a month and haven't seen anything like a cave in this game.

Thanks Marlonette

No seriously, when you see one you'll know that's the one. Try going to Volcano Veteran 3-3 and scroll around the map. Check out all the tiles and voila!

And it's not Marlonette...

As Marionette said, it will be obvious when you see it. It will stand out since you most likely haven't seen it yet and you're familiar with the other tiles.
Nonetheless, it looks like a mossy brown rock with a hole.

Okay great thank you both for the help I completely understand now and sorry Marionette.. I'm on my ipad and it looked like an l in your name although I had spelled your name right at first but chanced the I to l..
