Strange work of range selector at Secondary Structure Prediction

Steps to reproduce:

1. Open /data/sample/PDB/1CRN.pdb
Expected state: Sequence is opened
2. Do context menu "Analyze - Predict Secondary Structure"
Expected state: Predict Secondary Structure dialog is appeared
3. Set "Range Start" 20, "Range End": 46, set any prediction algorithm
4. Press "Start prediction" button
Expected state: you get annotation(s) in range 20..46
Current state for GOR IV: you get annotations with ranges 11..15 and 24..25

May be need remove Range Selector from this dialog.
