Mcreator Version 2023.2 Has A bug

In Version 2021.2 the one i had before upgrading I could name my mod file this TheOffcialOvergrownMod4.7.3 And It Would Still Be A Jar File. But In Version 2023.2 I Did That And It Turned Out As a 3 File because The End Of Is Named .3 Instead Of Making It A Jar File. Even Thought It Said It Was Saving it As A Jar File And This Is Really Bad For Me. Becuase The Mod Cant Be Uploaded As A 3 File.
