Hello all, 
I'm new to this forum and hoping you can help solve my problem. First of all, I'm not a native speaker and I'm mainly self-taught (but have been shooting for 10+ years) so I might not know some technical lingo. I'll try to explain as best as I can but please bare with me. 

I shoot gigs and bike races with my Nikon D750 (fx mount). I typically use back button focus for gigs and shutter for bikes. It works great, never had any issues.
 
Yesterday, I was shooting an event and swapped to my Sigma 8mm lens that's from my old kit, so a dx mount. Not an issue, great shots. But when I switched back to my 24-70 fx lens, I noticed the back button focus was gone. Reset it quickly, but I realised I don't have the outline guide - black lines + a small red square - in my viewfinder I normally move around to pick my focus point. The square is present on the screen but that's too slow for gigs so I use the viewfinder. 
 
I looked into AF area modes and numbers of focal points, reset my camera to original settings etc but no luck. Spent ages googling but again, no luck. 
 
Is there a wise person here who knows how I can solve this?
 
I turned it off and on again, battery out etc. I gave the sensor and mirror a good clean too (post festival bath lol), but still nothing. Is it the heat? Is it because I just shot a 3-day festival last week (no damage to the camera though)? I didn't drop it, I didn't leave it in the sun or anything that could damage it really.

Thanks a lot for your help!

What are your settings for custom functions a4, a5 and d7? They don't always reset when you do a quick reset.
