Build error

[Hannie Dumoleyn <lafeber-dumoleyn2 zonnet nl>]

On https://l10n.gnome.org/vertimus/gnome-user-docs/master/gnome-help/nl/ 
I get the following error message:

Build failed (itstool): Error: Could not merge translations: Entity: 
line 1: parser error : Opening and ending tag mismatch: gui line 1 and p 
Entity: line 1: parser error : Premature end of data in tag p line 1

In terminal I tried this:
msgfmt -cv -o /dev/null 
gnome-user-docs-master-gnome-help-nl-241183.merged.po

Reply: 2593 translated, 516 fuzzy, 208 untransated.

I opened the .po file in Gedit, but there is no tag p in line 1.

Can anyone help?
