I've been seeing this reported a lot on various Facebook groups over the past two weeks but have yet to see an answer. All I can advise is that its works fine for me (with one odd texture.) My advice would be to remove it completely and:
 
1. Install EUP - Law & Order 8.1 by Alex_Ashfold first.

This is the main modification and a straight forward .oiv package, so just run it via OpenIV.

2. Next, I install EUP Menu by PieRGud.

This provides you with the in-game menu (opened via F11 by default) that you can use to instantly change your character's uniform. You can choose from several agencies with pre-made outfits. You can also set and save your own outfits for quick use. For example, I have my LSPD uniform saved here along with the same uniform plus a set of gloves. In-game, I can quickly 'wear my gloves' when conducting searches etc and then remove them. Simple and immersive.

This is all you need to actually use EUP, however I recommend also using the following.

3. EUP - Serve & Rescue by Alex_Ashfold.

This small mod is an addon to step 2. It provides you with additional outfits to choose from including fire-fighters, coastguards, janitors, prisoners and coroners. It is also an .oiv package so really easy to install.

4. LSPDFR EUP Configurations by Alex_Ashfold.

This is the mod that actually applies some of the EUP Outifts for your character but also for NPCs (ambient spawns and backup). It can be used 'out-of-the-box' or it can be customized to fit your needs.
 
It is worth pointing out that you'll want to be running LSPDFR 0.4+ (I'd recommend using the latest build 0.4.1).
