I don’t think it is a service issue.
These are configurations, maybe overwritten resetting to default settings in case of troubles.
E.g. in my case I open the app launcher with windows key with a Latte configuration like here (search Latte in application launcher, then preferences). But when I have to reset Latte, it gets removed.
For other shortcuts, I don’t know what you need and have.
You should search for shortcuts in system settings and you’ll find something like this (only an example to show alt+tab):
