Dragoon Jump Macro and item not working

So I'm sure alot of us know about the /macroicon "insert ability" but maybe not, to you that do understand I am reaching out for your help. Here's my issue:

/macroicon "Jump"
/ac "Power Surge" <me>
/ac "Jump" <t>

This macro by all means should show the tooltip and cooldown of Jump, ability of dragoon, and also should use power surge on first push and jump on second push. Sadly all it displays is the "M" key. The only conclusion I can come to is that since there is another "jump" command in the spellbook, which is actually the spacebar jump command, causes the tooltip to not understand which icon to use. Has anyone discovered a work around or fix for this? The macro works fine if I have "Spineshatter Dive" in there, so I know it works.

Now my second question. Just attempting to clear up space I tried making a healing macro.

/macroicon "Second Wind"
/ac "Second Wind" <me>
/item "Mega-Potion" <me>

Simple enough, second wind goes off just fine but it doesn't understand the item command. So I changed "-" in it, tried lower case, tried using <t> and nothing. I even tried putting the most basic macro:

/item "Potion" <me>

Still nothing. If anyone knows what I'm doing wrong here please help me understand lol. Thanks in advance. ^.^

try

/ac "Second Wind" <me>
/wait 1
/item "Mega_potion" <me>

ability and item usages have a cast/channel time, without the /wait 1, the macro tries to immediately use the second ability which fails because you are currently in the middle of the animation of the first ability. Adding /wait 1 gives the system enough time to cast the ability animation of the first /ac while initiating the next.

If that's the case it doesn't explain why this doesn't work.

/item "Potion" <me>

Also I'd rather not have the /wait 1 in there since I don't want the macro to use the pot and the ability for me. I simply want it there in case second wind wasn't enough of a heal or if I get hit later and second wind is still on cooldown. The macro is just to free up space that's all. I'm not sure why even this basic potion macro isn't working.
