If the character is attacking the mob when the mob comes into melee range, then the only thing I can think of is you need to make sure that CampRadius is less than MeleeDistance. If CampRadius is greater than or equal to MeleeDistance then the character will NOT move to the mob. That is by design, so check your settings. Just to test I would set CampRadius=35 and MeleeDistance=75 and increase MeleeDistance if needed. Another thing to consider is when you are in chase mode. When in chase mode the characters current .X, .Y, .Z is used as their Camp Location, and when checking if the character is ready to move to the mob, before attacking, is determined based on the Mobs position/distance from the MA. When the mobs is CampRadius close to the MA then the character should move to engage. When ReturnToCamp is on ChaseAssist should be off, and when ChaseAssist is on ReturnToCamp should be off. There is only one situation where both ReturnToCamp and ChaseAssist should both be off and that is when using the /waithere command. But never should both ReturnToCamp and ChaseAssist be on at the same time. If you are using the /waithere command. Then you should be using either the /chase or /camphere commands to recover.
