Running Umbraco 4.11.5 & Courier 2.7.5.1

When deploying a single node and not selecting any dependencies, everything comes back green but I'm getting the following error in the logs:

<p>The ability to access good facilities within the local community is vital to any sports organisation, yet many clubs struggle to find places to play and train.</p>
<p>A large number of sporting facilities are located on school sites and making these available to sports clubs can offer significant benefits to both the school and the local clubs.</p>
<p>Sport England has produced toolkits to help open up school sites for community use, this guidance will ensure that the process is a smooth one for both the sports organisation and the school.</p>

</ul>

Any ideas ?
