To reproduce:

• Go to a page like Феофанія (it contains a template Шаблон:Картка:Парк, where Шаблон: stands for Template:)
• Press Редагувати, to open it in VE
• Click the template on the right and press the Редагувати button on its bottom to open the template editor.
• On the top of the dialog you'll get the template's name :Картка:Парк Which is already wrong because it contains a colon in the beginning.
• The description says:

Ви додаєте шаблон «:Картка:Парк» на цю сторінку. У нього ще немає опису, але може є якась інформація на сторінці шаблону.

which is

You are adding the ":Картка:Парк" template to this page. It doesn't yet have a description, but there might be some information on the template's page.

in English.

You can see that the template name here is wrong again because it contains a colon in the beginning, which becomes a double colon when you try to go to the template's page and get a badname message instead.
This happens to all the templates of this type. All the other templates work just fine.
