Domain Templates Broken 8.0.1

[artm]

After trying to create a new domain template, I ended up with a corrupt template (no title line, not configurable)

When I try to remove it I get:
ERROR: PleskFatalException
TemplatesList::remove() failed: TemplatesList::getRepositId_() failed: Unable to define templates

0: /usr/local/psa/admin/plib/common_func.php3:174
psaerror(string 'TemplatesList::remove() failed: TemplatesList::getRepositId_() failed: Unable to define templates')
1: /usr/local/psa/admin/htdocs/creation_templates/dom_templates.php:57

Any ideas how to fix that?
