After updating to Xubuntu 18.04 I was quite surprised to find out that ott templates are not linked to documents any more.
It might be, that now the templates are not where the document expects it. The information about the template is in a node meta:template in the file meta.xml in the document package. [You know, that a document is actually a zip-container?]
Now compare, whether the path, which is listed in the file, would go to the template in your LibreOffice installation.
