TOPIC: 1 value tide correction used instead of tide curve

Hi. I am trying to correct the bathymetric data using a tidal station. The tide station has temporally coincident data with my bathymetric data. However when the tidal correction is applied a single value (in this case -0.14m) is applied to the entire dataset, not the correct temporal tide value. The attached images illustrate that for both points the tide correction is listed as -0.14m. The second location tide correction value should be -0.08m. For other lines in this workspace the tidal correction was applied correctly. Does anyone have any possible ideas as to the problem?
Thank you.

Hard to say where the problem is without more information, but the most likely is probably a timing issue. If the 0.14 correction is at the beginning or end of your tide correction data then that value will persist ("last value interpolation") when correcting all points before or after the time period covered by the correction data.
