[4.x]: Unable to reset config value to craft default

[samhibberd]

What happened?

After recently changing a setting in the commerce general settings in the control panel (we very rarely change settings in this way), I noticed a bunch of changes in the project.ymal, it saved all the values from my commerce config file to this file.

Subsequently removing / commenting out a config value from the commerce config file, like pdfPaperSize:

return [
    'pdfAllowRemoteImages' => true,
    // 'pdfPaperSize' => 'a4',
];

The config setting when accessed via php or twig, remains a4 rather than reverting to the default letter which I would expect to be the default behavior?

Resaving the commerce General Settings does not fix this.

Could this be related to any changes here - https://github.com/craftcms/commerce/issues/3632

I could not reproduce what you are seeing. I added:

<?php

return [
    'pdfPaperSize' => 'a4',
];

in commerce.php and in my pdf template I put:

{{ craft.app.plugins.getPlugin('commerce').settings.pdfPaperSize }}

which returned a4 (I have 'letter' in my project config).

When I commented it out:

<?php

return [
//    'pdfPaperSize' => 'a4',
];

The pdf returned 'letter'.

Could you try again and let me know?

Just to confirm, did you save the Commerce > General Settings before you commentend out pdfPaperSize?

@samhibberd I will give it another test now and let you know.
