Group Category Creation > Group Creation Access : Selection Box

Hi Team,

I found an issue while trying to create a GROUP Category from backend. I am using Joomla 3.2.3 with default backend template.

Please find the two images I have attached. The one with a Dropdown menu accept only SINGLE selection (default layout under J3.2.3). I've read from the description for Group Creation Access and guess this should be a multiple selection box.

Checking to code I have:
<select class="form-control input-sm" autocomplete="off" name="create_access[]" id="create_access" 1="" style="height:150px;">
<option value="1" selected="selected">COM_EASYSOCIAL_ID_PROFILE_RUSER_TITLE</option>
<option value="3" selected="selected">COM_EASYSOCIAL_ID_PROFILE_RCOMP_TITLE</option>
</select>

Not sure why the MULTIPLE option is missing with the select tag. I have added it back and now it works.
MODIFIED:
<select class="form-control input-sm" autocomplete="off" name="create_access[]" id="create_access" 1="" style="height:150px;" MULTIPLE>
<option value="1" selected="selected">COM_EASYSOCIAL_ID_PROFILE_RUSER_TITLE</option>
<option value="3" selected="selected">COM_EASYSOCIAL_ID_PROFILE_RCOMP_TITLE</option>
</select>

Guess something strange with J3.2.3 since I am only using a default backend template.

Please advise this is isolated issue or a program bug? Further, I found another issue... Click the [CANCLE] button in the Group Category Creation page will leads to an Page 404. (Because I run my backend site with http://www.domain.com/folder/administrator/ and clicking this specific CANCLE button leads to http://www.domain.com/administrator/

Thanks
