Describe the bug
A clear and concise description of what the bug is.
EPA STORM WATER MANAGEMENT MODEL - VERSION 5.2 (Build 5.2.4)

ERROR 363: invalid data in external file used for Time Series DARWINAirport.

To Reproduce
Steps to reproduce the behavior:

1. Go to Temperature Page
2. Click on Time Series and Then Edit the Time Series
3. Enter the Time Series Name, Point to a file, hit OK
4. Now go back to the Temperature Page and Try to Select No DATA
5. Now when you run, the previous data is still referred to, even though I do not want to use any data ?

Expected behavior
A clear and concise description of what you expected to happen.
Once I select NO DATA, I expect the previous INPUTS to be deleted ?

Screenshots
If applicable, add screenshots to help explain your problem.

I cannot reproduce the behavior you describe. However, I have a few suggestions and comments

1. You appear to be describing a problem with the GUI, which more properly belongs at https://github.com/USEPA/swmm-gui
2. AFAIK no one at US EPA currently maintains SWMM. All the staff that had worked on it have left the agency and the Office of Research and Development has been shuttered: https://www.science.org/content/article/blow-environment-epa-begins-dismantle-its-research-office . Both this Github site and the GUI site are owned by EPA without access by others for code development.
3. If you are trying to load daily max/min temperature data, I suggest instead using SWMM's external climate file format , such as demonstrated in www.openswmm.org/Topic/11888/evaporation-snow-and-groundwater-processes. I've attached a file for Darwin Airport as obtained and processed using NetSTORM (www.dynsystem.com/netstorm) from NOAA's (US met data agency) GHCN repository.
4. If you are trying to load hourly temperature data, you should be aware that, unless I'm recalling incorrectly, while SWMM can perform snow process calcs using hourly data (seems to be an unlikely application in Darwin!), it can only calculate evapotranspiration from daily max/min data.
