KeyError: 'replace'

[meiyang12]

I ran gff3_merge program, and I got the error

Traceback (most recent call last):
  File "/home/meiyang/anaconda3/bin/gff3_merge", line 33, in <module>
    sys.exit(load_entry_point('gff3tool==2.1.0', 'console_scripts', 'gff3_merge')())

and my gff3 files were like these: one:
