The created peers disappear from the wg-manager after a while

[portg80]

Describe the bug
The created peers disappear from the wg-manager after a while. The configuration file remains in the folder, but it is not in the menu. It is not possible to connect via the disappeared config, so you have to create a new one.
To Reproduce
Steps to reproduce the behavior:

1. Create a configuration for a new client
2. Connect successfully
3. After a while, when connecting via this config, there will be no internet connection.
4. When logging into the remote server, open wg manager (bash /usr/local/bin/wireguard-manager.sh )
5. Select the "delete peer" option and the created config will not be in the list of peers available for deletion.

Expected behavior
I expected that, like the rest of the configs, they would not disappear spontaneously.
