"Provoke" Macro doesn't always perform "Provoke" action

[Laraul]

Time: Any time
Frequency: Occasionally
World name: Hyperion
Character name: Laraul Lunacy
NPC name: Any
Monster name: Any
Class/Level: PLD/50
Party or solo: Party
In-game time: Unknown
Area and coordinates: Any location/instance/RAID
Steps
1. Create the following macro and test it repeatedly. (Windows version)

/macroicon Provoke
/macrolock
/macroerror on
/action Provoke
/party Provoke (<recast.Provoke>)  <t>

The proceeding macro doesn't always activate the "Provoke" action when triggered. Occasionally there are times I must repeatedly press it before it performs the "Provoke" action. When this happens I see the following in my log window.

[10:50](Laraul Lunacy) Provoke (--:--)  Nael deus Darnus <se.13>
[10:50](Laraul Lunacy) Provoke (--:--)  Nael deus Darnus <se.13>
[10:50](Laraul Lunacy) Provoke (0:40)  Nael deus Darnus <se.13>

This text is generated by the last line. It shows my target, and the recast time for the action "Provoke." "(--.--) = no recast, (0:40) = 40 seconds until next use (i.e. just activated)" I never see any error message explaining why the action didn't perform properly.

When I use the action only (no macro) it ALWAYS activates.

This is the only macro I have that is not working properly. It's been an issue for quite sometime (almost a year since I first encountered it). I've tried making minor alterations, hoping I could get it working every time instead of 50/50. Nothing I've tried works.

Here's an image of the macro for reference.
