The issue also needs to be fixed in [CustomfolderlistField.php](https://git.vdm.dev/joomla/Component-Builder/src/commit/8548530b6da9494470cdc7e095e7f215c0d26ff2/admin/src/Field/CustomfolderlistField.php#L53) since the new release only fixed it for [CustomfilelistField.php](https://git.vdm.dev/joomla/Component-Builder/src/commit/8548530b6da9494470cdc7e095e7f215c0d26ff2/admin/src/Field/CustomfilelistField.php#L50).
I installed the [v5.0.0-alpha5](https://git.vdm.dev/joomla/Component-Builder/releases/tag/v5.0.0-alpha5) and editing the Demo Component files & folders still didn't work until I also fixed the issue in the [Customfolderlist.php](https://git.vdm.dev/joomla/Component-Builder/src/commit/8548530b6da9494470cdc7e095e7f215c0d26ff2/admin/src/Field/CustomfolderlistField.php#L53).
The new releases of [v4.0.0-beta3](https://git.vdm.dev/joomla/pkg-component-builder/src/tag/v4.0.0-beta3) and of [v5.0.0-beta3](https://git.vdm.dev/joomla/pkg-component-builder/src/tag/v5.0.0-beta3) fixes the problem.
