Runeword bulwark not working

What the hell. Despite not having the ladder seasons anymore I saw as of 2.6 ladder runewords can be made across the board. As such I thought this would be a good time to try and make BULWARK which would be a great asset to my warlock. Turns out I wasted 3 very hard to get runes. Please help!

All Runewords are available anytime for offline. But for non ladder it isnt available.

It was mentioned if new runewords were introduced for Ladder. Previous ladder runewords will be available for non ladder.

We got runewords for non ladder. So above rule doesn’t apply.
