Description
When using /sell hand while holding lapis, the item will be sold as an inksack. When using /shop and navigating to the corresponding shop that buys lapis it will also show as an inksack, with the lapis sprite. However if the player goes to the physical shop they will be able to buy lapis like normal.

If I do /give <user> lapis then that user receives lapis, but the chat says it's giving the player ink sack.

Steps to reproduce
Sell lapis using /sell hand or give lapis using /give <user> lapis

Expected behavior
The user being able to sell lapis as lapis, and get the proper price for them

I can confirm that this is a bug and not only Lapis gets sold as inksacks, it's almost every dye that is in Minecraft. This is because every dye including Lapis is minecraft:dye but with an extra numerical value. You can test this by executing /minecraft:give [Username] minecraft:dye 1 4 this command will give you Lapis and /minecraft:give [Username] minecraft:dye 1 0 will give you inksacs so I think the cause of this issue is EssentialsX not reading the extra numerical value that the item has.

This should be fixed on MineCraft 1.13+ by the sheer fact that lapis is now it's own item, rather than being lumped with the other dyes (which stem from ink sack). I don't believe this will ever be fixed in prior versions, since it hasn't already been fixed until now.

To clarify: on older versions of Minecraft, EssentialsX will use the value you set for each data value of each material in worth.yml. On 1.13+, EssentialsX will use the value you set for that material, as data values don't exist any more.
