Lake inflow/outflow masked values

[Alfred Zhong]

I'm running WRF Hydro with lakes turned on and I occasionally get masked values (printed as --) for the inflow / outflow values for the lake. Has anyone run into this issue before? What may be causing it?:

202409240000 1 > water surface elevation above sea level 330.17523 m > inflow 346.97537 > outflow 347.0229
202409250000 1 > water surface elevation above sea level 330.73187 m > inflow 415.5643 > outflow 415.63995

202409290000 1 > water surface elevation above sea level 350.5347 m > inflow 4825.1826 > outflow 4826.4824

202410010000 1 > water surface elevation above sea level 333.9593 m > inflow 892.99915 > outflow 893.0858

This also seems to be a problem with the archived NWM reservoir data I found on Google cloud at https://console.cloud.google.com/marketplace/product/noaa-public/national-water-model:
