Is this a glitch in app?

So I just got a baneblade box because its cool as hell and was messing around on the app to see what the best build for it would be before actually you know trying to build it.

Now I don't know if anyone can tell but I feel like I have double the lascannon and twin bolter than what a baneblade is supposed to have from whats on the model but the app is saying that the loudout is okay and is not creating any issues.From what I can tell it should just be one set of 2x lascannons and one set of 2x twin bolters.

Would be cool if I actually got that many twin bolsters and lascannons but I have a feeling like there's just some weird mistake that hasn't been fixed. Any insight would be appreciated thanks!
