length tag not properly shown in html

It seems that some of the tags doesn't properly work when exporting to HTML.

I have added

            <th class="title">Title</th>
            <th class="title">Bitrate</th>

            <td$if($odd(%_counter%), class="odd",)>$replace(%title%,&,&amp;)</td>
            <td$if($odd(%_counter%), class="odd",)>$replace(%bitrate%,&,&amp;)</td>>

But in the column for bitrate I see some integer number 1723338 (even not all of the rows contain lenght). However the length should be in form of mm:ss

I cannot see the _length field in your export.
Also, I do not see in my export that the _length field does not comply with your preferred format.

Excuse me for the typo while writing the snippet. But I got it!
I wrote

<td$if($odd(%_counter%), class="odd",)>$replace(%length%,&,&amp;)</td>

and now I chang it to

<td$if($odd(%_counter%), class="odd",)>$replace(%_length%,&,&amp;)</td>

and it is fine. Many thanks
