Unveiling mod displays "The Operation Could Not Be Completed"

As the title suggests, when going to Jun to unveil a modifier on an item dropped by a Syndicate member in maps (was a level ten map), selecting confirm results in an error message in red text stating "The Operation Could Not Be Completed" being displayed. The selected modifier appears on the item but is not craft-able from the hideout bench.

No idea how to upload images so I'll describe it as best I can:

- When unveiling, the modifier being selected appears with a yellow line as if I have already unveiled it at that tier.

- Selecting confirm then shows the modifier with a white line as if I haven't already unveiled that mod at that tier.

>> e.g. similar to this thread but I believe you said that is a UI thing https://www.pathofexile.com/forum/view-thread/2770028

- The tier of the modifier being unveiled is not increasing in tier (e.g. tier 1 to tier 1)

- The modifier itself appears on the item but does not appear on the craft bench.

Notes:
- Observed with Jun whilst in map and in hideout
- Re-logging did not resolve the issue
- Don't believe it is item class specific (seen with rings and helmets)
- Whilst unveiling the modifier, it is not possible to remove the item until after I have unveiled the mod
- In some cases if I have unveiled the modifier selected already it will have new, higher lower and upper bounds of possible values to roll than the recipe on the hideout bench however the tier is the same
e.g.
>> Existing recipe on bench - tier 3 increased energy shield (18% to 21%)
>> Unveil option - tier 3 increased energy shield 28%
- The craft bench would not show any recipes

Experienced the same, unsure if it's a bug or my noobness. But yeah, all modifiers are at level 3 when trying to unveil and then "The Operation Could Not Be Completed"

any solution/workaround for this problem?
its so sad not to learn anything from such seldom items ;-/

There's no problem. You can never get the same mod on the bench as you get from unveiling.
