By default, the makeDIST_RST program assumes a lower bound of 1.8 angstroms.
This makes sense for ordinary "NMR" restraints between atoms that are not
bonded to each other.

If you have upper bounds (as above) of 1.61 Angstroms (!), you will have to
either create the restraints by hand, or manually modify the DISANG file for
these unusual restraints.

...good luck...dac
