Addon Installation doesn't work

Hi, I want to set up a new HA. I’m using an Odroid N2 with OS Installation. I followed these instructions and installed the OS on a eMMC module. ODROID - Home Assistant.

HA is running, so far, so good. But if I want to install addons I have a problem. If I go to the addon store and install an addon (e.g. SSH & Web Terminal) it seems to be installed. But is I go back to the addon store nothing is listed.

If I install an addon and open the configuration everything looks normal, but if I change something, e.g. add a password and click save, I get the message “There is no configuration for this addon”.

If I activate all options, like Watchdog and automatic update, and click start, every option gets deactivated. But in case of the SSH terminal it is shown in the sidebar and if I click on it it seems to work.

This is just an example with the SSH addon, but I have similar issues with any addon

I found the answer. I need to press Ctrl+F5 after I installed an addon
