That's a lot of airplane for no BVR missile capability.
Well, the F-4F was a stopgap solution to begin with due to the delays in the Tornado program, and as the version of the Tornado the Luftwaffe was considering did not include BVR capability they did not want to pay for that in an interim aircraft either. MDD was probably anxious to cut the costs (and thus sales price) anyway in order not to have Luftwaffe buy eg. Viggen (of course, Luftwaffe did not need to tell them that they did not want another single-engined aircraft, no matter how cheap) or Jaguar instead.
That does not of course explain the other half of the order, which was used in dedicated air-to-air role, but as it was supposed to supplant the attrition of the F-104 force, the capability was replaced like-for-like.
The cynic would say that this was how the acquisition was sold to the politicians, as in a few years Maverick capability was (re-)added and in less than ten years the Luftwaffe would initiate the ICE program which actually modernized the F-4F's beyond any US Phantoms (APG-65 radar, the same as F/A-18, and AMRAAM capability, among many other improvements).
