Fill to 1/4" to 1/8" below the split ring that extends down into the cell. Fill after fully charged as the electrolyte will expand as it charges. Although the plates need to be covered before charging. Just touching the split ring is absolute max and may still have some electrolyte pushed out and cause corrosion. Swelling and wet of one battery sounds like a shorted cell and is fairly common.
Charging voltage can make the issue worse. Plenty of equipment charges at a voltage too low and floats at voltage too high. Post the converter or charging equipment make and model number for best answers. Also make sure the battery is not allowed to discharge below 12.0 volts while in storage. Float at 13.2 will work well for storage. May need to get a voltmeter to verify actual conditions.
I recommend LFP replacements next time.
