Why do changes in Bitrix Small Business disappear at midnight?

Question

1C-Bitrix

Does anyone know the reason why the Bitrix Small Business edition returns those settings of components and properties that were before the changes or accepts partially. Those. in the property, for example, check the multiple box. There is no tick in the morning. Or add a property. The property is there, the "active" checkboxes are not. Or we upload new styles via ftp, first they are there. Everything works fine, but in the morning it doesn't. The cache is disabled. There were no mistakes. The system was checked. In the logs, except for me and the crowd of garbage bots (client's choice) - no one.
