Flik's effect is intended to destroy all copies of a chosen minion, wherever they are. However, the game has many cards which are meant to be considered the "same", despite differing card IDs. This can include the Doom in the Tomb event cards, the two differently dressed Doppelgangsters summoned by the battlecry of the first, the thirty Jade Golem minions with incrementing stats, or tokens that are meant to be recycled from previous expansions (e.g. Annoy-o-Tron from GvG vs the one from Giggling Inventor.)
Matching on card ID has caused issues in the past due to this, so it seems that Blizzard decided to match on card name instead (like Caverns Below). Instead of false negatives though, this causes false positives:
This can also lead to him killing non-minion cards outside the battlefield:

(First bug shows a Mirror Image spell being removed when Flik kills a Mirror Image minion in play)
If you target a spellbender(minion), spellbenders(mage secret; 3-cost spell) in hand/deck also destroyed by Flik.
But spellbender(secret) which is on the portrait(battlefield) doesn’t destroyed by Flik.(both player control spellbender in above image)
It should be either
Spellbender(secret) doesn’t considered as a copy of minion-spellbender and doesn’t destroyed by Flik. or,
Spellbender(secret), which is controlled by player, also destroyed by Flik.
I also tried killing an adventure boss (Maexxna) by using Flik on the minion of the same name, to no avail.

(Wherein two slimes with different stats and abilities, one from Blood to Ichor, one from Sludge Belcher, are killed together by Flik).

It does not appear to affect non-minions in play, though: https://us.forums.blizzard.com/en/hearthstone/t/flik-skyshiv-bug-or-intended/20073
