LB Kemp autofill not working

Hello,

I'm trying to configure autofill on a Kemp LoadMaster LTSF load balancer, but the entry is not filling in the login fields as expected.

The device is a Kemp LoadMaster LTSF, and below is the relevant HTML code from the login page:

<table class="tab tabtab">

<tbody><tr><td class="lefttd">User</td>

<td class="righttd"><input class="Focus" id="xuser" type="text" name="user" maxlength="64" tabindex="1" autocomplete="off"

<input type="submit" id="xsub" name="logsub" value="Login" tabindex="3"></td>

</tr>

<tr><td class="lefttd">Password</td>

<td class="righttd"><input type="password" autocomplete="off" id="xpass" name="pass" maxlength="64" tabindex="2"

</tr>

</tbody></table>

Below are the settings I have configured in the entry.

Can you help?
