Missing xxx Modules message after cloning from repository

Hi, I have purchased a pack called [horror pack][1].

So when I view the uproject file,

{
	"FileVersion": 3,
	"EngineAssociation": "4.14",
	"Category": "",
	"Description": "",
	"Modules": [
		{
			"Name": "horror_pack",
			"Type": "Runtime",
			"LoadingPhase": "Default"
		}
	],
	"Plugins": [
		{
			"Name": "HGGifImporter",
			"Enabled": true,
			"MarketplaceURL": "com.epicgames.launcher://ue/marketplace/content/4b62266dcb0c4ffaac8e7ebdc61b4fba"
		}
	]
}

I see the Marketplace URL.

The uproject file and uasset files are versioned using Git LFS 2.

After pushing my work at GitHub, my fellow co-worker has cloned my UE4 project.

Then, my co-worker faced a problem.

I use UE 4.14.3 whereas my partner uses both UE 4.16.2 and UE4.14.3.

After cloning the latest commit from GitHub, my partner saw this message when the uproject file was opened with the Unreal Editor.

This message pops up regardless of the Engine’s version.

After clicking “Yes”,

Running C:/Program Files/Epic Games/UE_4.14/Engine/Binaries/DotNET/UnrealBuildTool.exe horror Development Win64 -project="C:/Users/PARTNER/Desktop/project/horror.uproject" -editorrecompile -progress -noubtmakefiles -NoHotReloadFromIDE

that message was shown from the log.

Luckily, the Editor opened the project successfully.

My question is, why does the Unreal Editor search for “UE4Editor-horror_pack.dll”?

Also, does this appear everytime after cloning commits from Git repositories?
