Where are the Gold Keys?

Hi folks, I have entered SHIFT-Codes for 8 golden keys on https://borderlands.com.
While my log for received rewards has an entry for each code with the number of keys, I have only 4 in game (on PS4). What’s wrong?

The codes are:
1 Golden Key: HXKBT-XJ6FR-WBRKJ-J3TTB-RSBHR
1 Golden Key: ZFKJ3-TT6FF-KTFKT-T3JJT-JWX36
1 Golden Key: Z65B3-JCXX6-5JXW3-3B33J-9SWT6
1 Golden Key: ZRWBJ-ST6XR-CBFKT-JT3J3-FRXJ5
1 Golden Keys: 9XCBT-WBXFR-5TRWJ-JJJ33-TX53Z
3 Golden Keys: ZFKJ3-TT3BB-JTBJT-T3JJT-JWX9H

When you redeem a SHIFT code for Gold keys it will send it to your mail. Check you social/mail to accept the Gold Key.

Redeem them in the in game social tab!

Got’em, thank you very much!

My question is, where are all the new golden keys?! C’mon Gearbox! We need moar LOOT! LOOTLOOTLOOTLOOTLOOT
