Is the configuration of email alerts buggy?

Good morning,

the administration interface seems buggy regarding the configuration of alerts.

Indeed, if I want to personalize the value of “alert_nag_interval”, the value is reset to 0 after clicking on “saved” then refreshing the web page (as well as all the parameters highlighted in yellow).

thank you in advance for your help

Hello, following server update to version 2.5.32 the problem is resolved. THANKS.
