Hello,

 When I write in a topic some text like this:
This is a set of $tests:Test$$ about a process.

And in the Glossary: 
Test: Meaning of test.

After generating the PDF booklet this is the result:
This is a set of Test about a process.

Instead of the correct result should be that:
This is a set of tests about a process.

When using the $$ to link a phrase to the glossary you only need to surround the Glossary term in $$ for example $$Test$$ and not the definition.

 If this doesn't resolve your issue or I have misunderstood in anyway could you please send us a copy of your project or some more details to support@innovasys.com and we will work to resolve yuor issue.
