Ducky keyboards have Cherry stabilisers.
They have a stabiliser bar running under the plate that is connected to the two pseudo-switches on either side of the space bar.
Under the space bar are three stems. One connects to the actual switch in the middle, the two outer ones connect to the stabilisers on either side.
Normally the spring in the switch pushes the space bar up, and the space bar pulls the stabiliser ends up too.
If you remove the space bar, it is quite normal for the stabilsers to drop down, as there is nothing holding them up.
When you replace the space bar, make sure you not only push it down onto the switch, but also push down each end so that it connects properly to the stabilisers.
