The problem is due to the SMIRKS itself.
The reaction is not applicable for this target substarte "COC1=C2C=CC=CC2=CC(=C1O)O" since it contains two fuzed aromatic rings, but the smirk defines two substritients to the atomatic ring with single not atomatic bond:
(-[!#16:6])
-[!#8!#16:5]
According to the official SMARTS/SMIRKS syntax by default supported in Ambit,
bond '-' means single NON AROMATIC and that is why these substituents does not match the aromatic substituent because the aromatic cycle is fuzed to another aromatic cycle
Solution:
Use insted of '-' bond deafult bond (e.g. nothing: CC instead of C-C) which means single or atomatic bond:
([!#16:6])
[!#8!#16:5]
