Hi,

You've discovered that the "Quotation Date" label is missing from Sales Order quotations in Odoo 17.0, even though the field is present and the label is visible in Odoo Studio when showing invisible elements, but you can't make it visible by clicking on it. This could be due to several reasons, including a CSS styling issue, conditional visibility rules, an inheritance problem caused by a module, a translation issue, or even a glitch with Odoo Studio itself.

To troubleshoot, start by checking the CSS styling using your browser's developer tools to see if any rules are hiding the label. Examine the label's properties in Odoo Studio for any conditional visibility rules. Temporarily disable custom modules and themes to see if they're interfering. Verify that the "Quotation Date" term has a translation for your language. Try a different browser and clear your browser's cache. Ensure you're using the latest version of Odoo Studio and check the Odoo server logs for errors. If none of these steps work, contact Odoo support for further assistance. If you find a CSS or inheritance issue, you may need to modify the CSS or view definition in your custom module, potentially requiring help from an Odoo developer.
