Can't change working folders cache files location 15 b6 & b7

In project Master settings, Resolve will not let me change the working folder location for cache files. I want to put it on a different drive. It did let me change the working folder location for gallery stills. When I attempt to save it, it simply reverts to the prior location.

Also tried to create a preset with the new location. Same result. No change on cache files working folder location.

Thanks!

If memory serves, you have to restart Resolve for those changes to apply.
