Minecraft v1.14.4
Forge v28.1.87
Better Crates v1.0.1
Crafting Station v2.1.1
Quark r2.0-199

• Crates might be missing localization, as seen from the crafting station mod image at the bottom, which displays the text "placeholder" instead of the Crate name. (Other mod inventories display normally.)

• Currently, the mod Quark in 1.14.4 adds a search bar to inventories, but in the Crate GUIs, the search bar overlaps the item slots. The same thing occurs with the mod Searchable Chests.

• My suggestion is to simply expand the top of the crate GUI slightly, which will allow the search bar to appear without overlapping slots.

Click on the Filter Button to display the search bar:

"Placeholder" text as seen in the side inventory.
