Two-part bug. As best I can tell, it happened when I took the hose connecting my Well to a Workshop module. First, the Well started displaying it's stored water as "NaN" and when I tried to fill a bottle using the panel during daylight it reported "Not enough stored." Then when I went to the pipe connection and tried to fill my suit bottle, it said "Filled to" but instead of the usual climbing percentage it gave a lengthy NEGATIVE number percentage. That water bottle now shows an empty bar in the Inventory interface, but it will not refill. Grinding off and replacing the Well got it working normally, but the bottle is still bugged.
