Task :compileJava FAILED, error: Modelwarden is not abstract and does not override etc., error: cannot find symbol

I am making a custom entity and I have pinpointed that the issue causing these errors is the custom Entity model I have been trying to use, I imported it to MCreator from Blockbench and as far as I know done nothing wrong, I made sure both File Name and Model Identifier are the same in Blockbench, and set it to Forge 1.15 - 1.16 (Mojmaps) (I already tried the other ones). And yes I have checked all the error forums and still cannot find a fix.  I have pasted the highlighted console below:
