If you use NBTExplorer, you can go into your world, then to level.dat -> data -> datapacks -> disabled, then click on Vanilla, and hit the red 'x' near the top. Hope this helps
Workaround
Make a data pack including all sign-related block/item tags
/data/minecraft/tags/blocks/signs.json/data/minecraft/tags/blocks/standing_signs.json/data/minecraft/tags/blocks/wall_signs.json/data/minecraft/tags/items/signs.json
Confirmed for 18w44a.
