Removing duplicate single substitution
0

Hi,

I am getting following errors while compiling feature or generating font from FontLab

[NOTE] Removing duplicate single substitution in 'init' feature: ttey, ttey.init
[NOTE] Removing duplicate single substitution in 'medi' feature: ttey, ttey.mid
[NOTE] Removing duplicate single substitution in 'fina' feature: ttey, ttey.final

I have checked there is no duplicate glyph or substitution for above letter ttey.
Please help.
