@oaramis Thank you for reporting this.
We have tried, but could not reproduce the issue with the stock Magento installation.
Please, provide preconditions (Magento version, settings you applied, etc.) and steps to reproduce.

[ishakhsuvarov]

@oaramis Closing this ticket for now.
Please feel free to reopen if the issue persists.

This also happened to me while developing a payment method.

Edit : Calling module:enable and module:disable on the custom payment module makes the bug appear or not, after investigation why the module generates this, it was a DI misconfiguration, a class name was misspelled.
