Probably the remainder of some wavelengths of the UV radiation is
stronger for the film than the visible light of fluorescentia.

Try Kodak Wr. 2C and/or 2E perhaps 3 if it possible. If not: a
double 2B, or a 2B together with a normal UV or Skylight filter
maybe useful. Additional CC filters would be necessary, or try a
negative film and correct it by printing.
