Why does my modpack download 1.9.4 binaries instead of a 1.8 minecraft.jar

[Hink]

My modpack seems to be downloading a 1.9.4 .jar file ever since I accidentally saved the modpack as a 1.9.4 pack. I changed it back to 1.8 and saved it. I then waited a while (24 hours) to be sure the modpack was set as a 1.8 modpack. It still seems to downloading a 1.9.4 .jar file. It has a 1.9.4.json file in the bin directory as well. I opened the minecraft.jar file and found out it was certainly a 1.9.4 .jar file since it had 1.9 textures and components in it.

[02:40:45] [main/DEBUG] [FML/]: Loading deobfuscation resource /deobfuscation_data-1.9.4.lzma with 31813 records
[02:40:45] [main/ERROR] [FML/]: There is a binary discrepancy between the expected input class aaa (aaa) and the actual class. Checksum on disk is 4e1fccd4, in patch 7691c467. Things are probably about to go very wrong. Did you put something into the jar file?
[02:40:45] [main/ERROR] [FML/]: The game is going to exit, because this is a critical error, and it is very improbable that the modded game will work, please obtain clean jar files.

I'm unsure of what to do to fix this.

Could not download said modpack, and shows up on the platform as a 1.7.10 modpack.
