Lightroom mobile iPad only importing 5 images at a time

This is an odd issue I'm having and I've been able to repeat it multiple times.  

I am attempting to import many (50-100) images from my SD card reader into Lightroom mobile for iPad. I have to import via files as it doesn't see the card reader as a camera. No issue there. But no matter how many I select it will only import 5 images max. These are Sony compressed lossless RAW files from an A1 camera. The imported images are fine (the ones that come in) 

Is there a reason for the importing capping out at 5 images? 

iPad is running 14.4.2 

latest version of Lightroom mobile. 
files are Sony compressed Raw lossless (roughly  52 mb each)
