Templater command in YAML does not automatically render anymore with new Properties (1.14)

Hello,

Since the new Obsidian update 1.14 with properties UI, I can’t render the creation and modification date in the YAML zone.
I still have Templater plugin up to date an active.

With the previous version of Obsidian (<1.14) :

Edit mode

creation: <% tp.file.creation_date() %>
modification: <% +tp.file.last_modified_date(“YYYY-MM-DD HH:mm:ss”) %>

Preview mode

creation: 2023-10-31 15:25
modification: 2023-10-31 15:26:06

And the modification date field was updating on file change.

With the New 1.14, it does not render anymore.
When I do a manual rendering (Alt+R) the command <% +tp.file.last_modified_date(“YYYY-MM-DD HH:mm:ss”) %> show “NaN”.
I have to erase the “+” on the command to render it correctly, but on file modification, it does not update.

I know that there is the Linter plugin to solve it, but I don’t understand why It worked well before the update and now it is just crap.

Have I missed something ?

Is it possible to make it work again withou using other plugins ?

Thanks for your help.
