Grenade after reconnect in my inventory again

Hi Guys,

We have the following issues with all types of throwable weapons (e.g. grenades).

I give myself 1x grenade and then have it in my inventory and in the weapon wheel. If I throw them, I lose them from inventory.

If I reconnect now, I have a grenade in my inventory again…

How can this happen and what can I do about it?
