[AMBER] Warning of sp2 improper torsion from Amber tutorial 1.1.4 "Building Protein Systems in Explicit Water"

I am using Amber 18 to follow the tutorial "1.4 Building Protein Systems in Explicit Solvent" (https://ambermd.org/tutorials/basic/tutorial7/index.php).
When I have done the tutorial and check my leap.log file, I find eight warnings like "** Warning: No sp2 improper torsion term for C*-CN-CB-CA atoms are: CG CE2 CD2 CE3". I have compared this to the leap.log online, which dose not contain such warnings.
Should I care about this? Or is it just resulted from the difference in Amber version?

Best regards,
