Mod not updating correctly

Hello! I made a server for Fossils and Archaeology, among other mods, and recently attempted to update the mod from 8.0.2 to 8.0.3 but deleting the old mod file and downloading the more up-to-date one. However, whenever I log into the server (With 8.0.3 installed both on the server and my client) it displays the mod version as being 8.0.2, which is problematic as this version has a pretty gameplay-breaking bug. How would I go about fixing this?

Can you please check the server log which version got actually loaded.

I for some reason cannot find the version the server loads, but it does mention that the client (me) is using the updated version, even though it displays the non-updated version when in-game.
