Cannot get poll icon to display next to topic title

Hi, I am using GD Topic Polls and GD Toolbox Pro together.

For GD Topic Polls, I have checked Poll Icon as ‘enabled’ (Show poll icon before the topic title in various topics lists), in the Settings > Integration menu.

In GD Toolbox Pro, under Settings > Topics, I have enabled the ‘Show Thumbnail’ option under the Forum Topics List part of the menu.

But no poll icon appears next to a topic name. Other icons that are used by GD Toolbox (ex: the icon indicating a user has posted in a topic) appear to work fine, and appear next to the topic name.

Can you help with this?

Thanks.
