new image TV never saved (image) for previously existing page

Hi,

I just experience a very annoying issue with a new image Tv I just created.
It's never saved .

• I just edit a page, go to the TV, open the file browser to pick up an image correctly seen in assets/images directory (previews are ok).
• The image appears now in the manager. (path assets/images/thefile.jpg)
• Save the resource.
• Re edit it again, this tv is no more populated..

Check in phpmyadmin the table, their's in modx_site_tmplvars a row for this tv (plus a few other one)



BUT NOTHING for this #5 TV in modx_site_tmplvar_contentvalues (only the others tv are listed here with their values).
The #4 tv is another image tv wich is ok.
I was in 221 and tried to update to 222, same problem.

PLUS: I just created a NEW page for testing purpose, the #5 image TV is working for it !
So the issue concerns only already existing pages

What's wrong ??

Thank you

New info:

Duplicating any of the pages that previously exist and then, managing the image tv to pickup the right image works.

really scaring
