You have to wait until LSPDFR/RAGE and Script hook to update. Typically it takes 5-6 days for all to update. I would suggest going forward so that you dont have to wait for the updates is make backup folder for your "GTA select, GTA V, GTA language and Play GTA" Do so, by copying all 4 from your GTA directory, and pasting it to a new folder on your desktop labeled whatever the game version is 2824, 2802. This way when GTA V updates, you FIRST make a new folder for the new update ie 2845 on your desktop, copy and paste all 4 files into that folder. Then drag the older version files from 2824 or 2802 folder into your GTA v directory into the buffer zone ensuring you're not hovered over any files. 

Hello, this sounds like it could be an issue related to the mods folder itself that Custom Vehicles are installed to.
 
A few things to try, first, try reinstalling ALL cars by simply overwriting the previous ones, open up whatever vehicle it is you're installing in the .zip, and do he normal install process as you normally would and see if that mitigates the issue.
 
Second, if that does not work, it is likely that you're better off rebuilding your mods folder, delete the mods folder and start clean, this is very simple and isn't very time consuming if you know what you are doing, especially when dealing with replacement vehicles.
 
Third, if you choose to take this step, note that depending on the amount of addon vehicles you have, it can be tedious but it may well fix the issue. its basically just overwriting the car files as I stated previously, however, this time open up your OIV and find each CUSTOM CAR you have (ex. police_hi.ytd) and delete that file along with the other corresponding file, do this for each custom vehicle and then proceed to reinstall the vehicles from scratch.
 
if you do not want to rebuild your mods folder then there isn't really much else I can tell you other than what I already have, usually issues like this are an issue with the mods folder itself not your game or OIV. Lastly, you should learn to install custom cars as DLC/Addons instead of replacements if you haven't already, they seem to be much more viable in terms of not breaking your game as long as you install the necessary prerequisites to install them. I hope this helps and sorry you're having this problem, unfortunately its the nature of modding GTA V since there is no and like never will be any native support for modding the game. 
 
Also, I noticed in your video that your vehicles were install in patchday28ng, mine are installed in patchday24ng, if you haven't, try relocating them there. Again, this can cause things to be a bit messy and knowing how GTA can be, may lead to game issues down the road, so you're likely better off with a fresh mods folder. 

alright bro, thanks
