Double-clicking bug

Has anybody figured out what the problem is with this double clicking RB thing. It's getting on my nerves dying in fortnite behind this bug. When I try to purposely make it double click by pressing it, nothing, but as soon as i get in a fight it wants
to activate this double input and switch my weapon slots to something like mini shields or whatever else. What is this problem and where is the fix this controller is $200 and hasnt even been out for 5 months yet.

Just to report in, on my scratch-built (Intel Core I7 Haswell CPU, Intel Mainboard, 32Gb G.Skill RAM, Intel 250 GB SSD) using a Logitgech wireless keyboard and Performance MX mouse, I have no problem. Double-click on a useable card in any of the games moves
the card. Card motion is smooth as is the little display after winning. All Windows 8.1 updates are present as near as I can tel.

I do have a Surface PRO 128 tablet and it does suffer the double-tap problem and card motion is twitchy and jerky.

Helen, hope this helps. MuddyJuddy, you probably don't appreciate it.

This is fantastic- thanks so much for this! @MuddyJuddy- is your PC also one that has touch enabled?

No touch capability on my PC.

A few specs for my PC if it helps: Windows 8.1 Pro with Media Center 64-bit (6.3, Build 9600) (9600.winblue_gdr.131030-1505), AMD FX(tm)-6100 Six-Core Processor (6 CPUs), ~3.3GHz, 8192MB RAM, AMD Radeon HD 6800 Series graphics, MS Sidewinder X3 mouse.

As a PS, I forgot to mention the system uses on board video and audio; no separate cards for either of those functions. Helen, if the research folks need the model number of the Intel motherboard I can get it for you. I just don't remember it.
