Well of Souls + Abyssal Echoes bug

So I was revealing a desecration on a body armour at the Well of Souls and I didn't like the options, and I remember watching a video earlier in the league of someone activating an Omen of Abyssal Echoes in their inventory AFTER revealing the mods and it still allowed them to reroll. So I decided I would test to see if this was fixed by going back to my hideout and buying one from Ange for 71 exalts, then headed back to the Well of Souls.

Upon opening the well again, I noticed my body armour was still there, but the mods had been hidden again. I thought that was weird, so I once again revealed the mods and was presented with the same ones as before. It seems anytime you reveal the mods, then walk away, it gives you an opportunity to know what the mods are going to be but allows you to walk away (and even take your item out of the well) BEFORE actually confirming your choice of desecration. Perhaps that was intended, but here comes a pretty big bug...

If you reveal the modifiers, walk away, activate an Abyssal Echoes, open the well again, re-reveal the modifiers, then the option to reroll doesn't appear. What's worse is, if you then take the item OUT of the well with the omen activated, it will eat up the omen even though you never got to actually use it.

I'm not sure what in all of this is intended, but I'm pretty sure that last part isn't, and it cost me a good chunk of currency. If it helps at all, I did all of this on a controller in the standalone PC version of the game.
