/targetmode, /tmode don't work when no subcommand is specified

From "Patch 1.16a Notes" thread:

* Targeting modes can also be activated using the /targetmode (/tmode) text command.
/targetmode(/tmode) [subcommand]
>>Subcommands
　a 　Switch to targeting mode A
　b 　Switch to targeting mode B
　Toggle between targeting mode A and B when no subcommand is specified.

Steps:
- I was doing nothing when the issue ocurred, just standing on the ground (I mean, no guildleve, behest, mission,...)
- Typed /tmode (without subcommand) and I got "/tmode" on my General chat window. Nothing occurred.
- Typed /targetmode (without subcommand) and I got "/targetmode" on my General chat window. Nothing ocurred.

Indeed. Only way this works is to specify A or B, so I assume this needs to be corrected.

Greetings, Umo!
Thank you for filling out the report regarding your concerns with the targetting mode command. I can understand how disruptive this can be, especially during battle, so I have made sure to submit your report to the development team for a thorough investigation. Any information made available regarding this investigation may be posted on this thread, so I recommend keeping an eye on it. Thanks again for your report!

Greetings Umo!

Thank you for your patience in receiving a response on your concern! We have received word back on this matter and wanted to give you a heads up as to the proper format to use this command. As of right now these commands are working as they are designed, the subcommand is needed to enact them.

/targetmode(/tmode) a
/targetmode(/tmode) b

Thank you for your time and your assistance in creating this report! We always appreciate it!
