tide forcing file errors

[Chang]

Hello everyone
I have prepared the tide forcing file following the instructions on (https://www.myroms.org/wiki/Tidal_Forcing/OSU Tidal Prediction Software Example (Matlab)) using OSU tide data.when i plot the constituent,i found there exist some errors.but i don't known what the problem is.
what i found is the amplitude of the four semi-diurnal tides exist very lager value so the plots are filled with single color--'blue'.The value present at west coast of korea but i mask it to water.i use the matlab MAX function to check the weird value which can be more that 100.
Could anybody here meet the same problem and help me? Thanks in advance.
