Gallery Settings not showing all

Hi guys,

I have a small problem with the Gallery Settings, there are 4 settings in the footer of the gallery applet, but I can’t use them but just two of them.
If I try to see the source of the frame there is no special CSS styling for the option that are not showing, but if I use Firebug I can see that the not showing options are <tr> elements with a “display: none;” style.
My questions are:
1. Why I can’t see this styling in the frame source code also?
2. What/who is generating this annoying element.style – “display:none:”?

Here I post the Firebug generated code:

<tbody>
	<tr style="display: none;">//this is not seeing in the source code
	<th class="label" scope="row">
		<label>
		<span class="alignleft">Link thumbnails to:</span>
		</label>
	</th>
	<td class="field">
		<input type="radio" value="file" id="linkto-file" name="linkto">
		<label class="radio" for="linkto-file">Image File</label>

		<input type="radio" value="post" id="linkto-post" name="linkto" checked="checked">
		<label class="radio" for="linkto-post">Attachment Page</label>
	</td>
	</tr>

	<tr>
	<th class="label" scope="row">
		<label>
		<span class="alignleft">Order images by:</span>
		</label>
	</th>
	<td class="field">
		<select name="orderby" id="orderby">
			<option selected="selected" value="menu_order">Menu order</option>
			<option value="title">Title</option>
			<option value="ID">Date/Time</option>
			<option value="rand">Random</option>
		</select>
	</td>
	</tr>

	<tr>
	<th class="label" scope="row">
		<label>
		<span class="alignleft">Order:</span>
		</label>
	</th>
	<td class="field">
		<input type="radio" value="asc" id="order-asc" name="order" checked="checked">
		<label class="radio" for="order-asc">Ascending</label>

		<input type="radio" value="desc" id="order-desc" name="order">
		<label class="radio" for="order-desc">Descending</label>
	</td>
	</tr>

	<tr style="display: none;"> //this is not seeing in the source code
	<th class="label" scope="row">
		<label>
		<span class="alignleft">Gallery columns:</span>
		</label>
	</th>
	<td class="field">
		<select name="columns" id="columns">
			<option value="2">2</option>
			<option selected="selected" value="3">3</option>
			<option value="4">4</option>
			<option value="5">5</option>
			<option value="6">6</option>
			<option value="7">7</option>
			<option value="8">8</option>
			<option value="9">9</option>
		</select>
	</td>
	</tr>
</tbody>

Thank you much!
