Question about HDD Mounting Brackets for Case

[Driver95]

Hey, this ones kinda hard to explain but i'll add a pic too so you can see what i mean

 

so, i recently bought a pre-build PC with some parts still missing that i build in yesterday, like a HDD, off i went and bought a Seagate Firecuda SSHD 3,5 Inch, the Case Manufacturer advertises the Case with two SSD Mounts and two 3,5 Inch HDD Mounts, no brackets or something are included and none were delivered from the manufacturer which partly build the PC for me. so i take a look at the case and see only 3 holes for screws on one side where i could ,,attach" the HDD to, i did that and im not really satisfied with the outcome because the HDD is a little bit wobbly if you apply some force and doesnt even touch the left side (seen in pic) where i could like add a bracket and screws so there a lot of space, what can i do about it, heres a pic of the manual and thats how i did it, is there anything i can do about it or shouldnt i be worried?

 

My Case is a Aerocool Bolt Midi-Tower.

It should be fine but do agree it really is not ideal. A second issue is that if you want to add/remove/change HDDs then you are going to have to pull the PSU out to get access to the screws.
