DB NOT CLEAN error with multiple diagrams

As we transition to the new Hyland Community, some post links may be temporarily disrupted as we finalize redirects. We apologize for the inconvenience and are working to resolve this as quickly as possible. Details.

When we have a single diagram, everything is OK, i.e.

<bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration" init-method="init">
        <etc…>
        <property name="deploymentMode" value="single-resource" />
        <property name="deploymentResources" >
            <list>
                <value>classpath*:/diagrams/Diagram1.bpmn</value>
            </list>
        </property>
</bean>

‍‍‍‍‍‍‍‍‍‍‍‍‍

Then we add a second diagram:

<bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration" init-method="init">
        <etc…>
        <property name="deploymentMode" value="single-resource" />
        <property name="deploymentResources" >
            <list>
                <value>classpath*:/diagrams/Diagram1.bpmn</value>
                <value>classpath*:/diagrams/Diagram2.bpmn</value>
            </list>
        </property>
</bean>

Now, each time we run a unit test file, we get the following error for the first test (only) in the unit test file:

java.lang.AssertionError: DB NOT CLEAN:

If we change the deployment mode to

        <property name="deploymentMode" value="default" />
‍‍‍

We do not get the error.  That is OK for testing, but my understanding (correct me if I'm wrong) is that a deploymentMode of "default" will cause all diagrams to be redeployed, and for production we would like to be able to add a new diagram without redeploying the existing diagrams.
Is there a way to add a new diagram without getting the error? 
Thank you.

I should have also said we are using:
- Activiti 5.16.3 with Spring configuration.
- h2 database with:
      driver "org.h2.Driver"
      url "jdbc:h2:mem:activiti;DB_CLOSE_DELAY=1000"
