What Is Adding Multiple Entries To Dropdown Menu?
 

It's not pChat.
It's not Junkee 2018.
It's not Inventory Insight.
It's not LootAlert.
It's not PersonalAssistant.
It's not ItemPreview. (Edit/Update: It was in fact ItemPreview, but not the only problem. So I got a false positive when tested.)
It's not LibMediaProvider.



I can't figure out which addon or library is causing multiple entries in my chat's dropdown menu.
When I had Master Merchant installed, it was even worse. MM had 3 entries for its price-to-chat feature and Inventory Insight had 3 entries as well.
Without Master Merchant, I'm down to just double entries from Inventory Insight.

Anyone know if there are specific addons known to cause this?
Or which libraries touch the dropdown menu?

Any tips on figuring out the culprit without disabling everything and re-enabling until it's found? :(

Addons addon to the context menus normally should use LibCustomMenu.

I only got 1 "IIfA: Search inventories" entry all the time so it's either a probem with your client language or another addon causing this, not using LibCustomMenu maybe.
Try if this happens with only IIfA + neede dependencies enabled as well.

You could start with addons using LibCustomMenu but I'm pretty sure these are not the problem but others not using it then maybe.

Found The Culprits!
 

One culprit is: ItemPreview.
Or more specifically: Rhyono's version. It still had the bug in it.

I would like to keep using Rhyono's version because it still allows me to preview things from my bags, but this menu entry thing sucks.

Another culprit is: Undaunted Pledges Utilities.

After disabling those two addons, my drop-down chat-menu is back to how it should be:


I've posted comments on both addons' pages.
