Sweep function gave an erroneous error message.

[subterranean1]

On 12/11/23 I attempted to perform a sweep function using Freewallet desktop for Windows. At the time of the sweep I had an XCP balance of approximately 1.49. Upon broadcasting the transaction I got the error message "Error composing sweep transaction via API: ['insufficient XCP balance for sweep. Need 311200000 XCP for antispam fee']

On 12/12 I purchased 30 XCP and sent it to my wallet. I again attempted the sweep and it worked without incident. The sending address is: 1AV3hDLsr7hLBkv9eWvFvsFNTCCNww9eAo. The successful transaction is: https://xchain.io/tx/be8b406d2093b5b3aa1212f884127c6d6b1b666541ef4d7ad50c511c08ae90bf and the total cost in XCP was 3.122
