Cannot see "Neutral" column anymore about resxresourcemanager

[malarres]

solved!
I had selected the option "Show an error message and don't load the resource" in the Configuration tab.

Then in the output I was seeing this error:

Error: System.InvalidOperationException: Duplicate keys in 'C:\my\path\to\Web.Sitemap.resx':
"Noticias.title",
(etc. etc.)

Given that the XXX.title and XXX.description always throw a warning

Note

Key names in global resource files should not include periods (.). However, periods are necessary in global resources that are referenced in site-map files when using implicit expressions. This is because of the resourceKey syntax. In some editing environments, such as Visual Web Developer, you might get a design-time error if you use a period in the key name. However, this shouldn't affect the ability to edit or save the file and can be ignored.

I was happily ignoring those. Bad move! D:

I'm leaving this here for reference to others (and for the future myself) but feel free to delete the (non-)issue if you wish
