Lost Loot Items After Buying Backpack Slots

Hey Guys,
I came across an issue in The Pre-Sequel. I imported my PS3 character into the PS4 version. After playing a bit I went and bought some backpack slots from the black market. After that I looked at my inventory and saw all of my inventory minus what was equipped has disappeared. Does anyone have any ideas on what to do?

Thanks,
Bill

Any Ideas on how to fix?
