Media Storage: First location is not where cache is stored.

I have a smaller SSD for my OS drive and this is where Resolve is installed(C:\).

In my Media Storage settings, I only have one mount listed, (E:\<dir>).
Resolve did create a CacheClip directory in the E:\ drive. However, whenever I go to create optimized media, resolve still creates it in the orginal storage location on C:\. C:\ is not even listed in the Media Storage Locations.

Is there another setting that I am missing to specify where the cacheclips go?

DaVinci Resolve Studio v15.0.0b.032 (Windows/MSVC)
OS Name Microsoft Windows 10 Pro
Version 10.0.16299 Build 16299
Processor Intel(R) Core(TM) i7-6700K CPU @ 4.00GHz, 4008 Mhz, 4 Core(s), 8 Logical Processor(s)
Total Physical Memory 32.0 GB
Video card name NVIDIA GeForce GTX 1070

Resolve is installed on a 446gb SATA III SSD

"Working folders" in "Master Settings" also specifies E:\Resolve Cache\CacheClip

Yet cache still goes to C:\
