CS Historically has sprung out of Math and EE departments so sometimes the Calc classes are there because historically they just where required to take it. However Calc is still needed for people in CS if they want to do signal processing (which is also done by EE's but CS people also tend to study this field) of process optimization. Things like Computer vision, Data Science, AI, ect also require Calculus. There are more fields too I just don't want to say them all here.
To sum up, Calc courses in CS programs have there roots in tradition and historical precedent but are still of use in fields of CS. Software engineers getting CS degrees wont need it but someone who wants to do serious work in the CS field need it.
