Joyce, 52, faces two charges of behaving in a threatening or abusive manner and a third charge of resisting police at Edinburgh Airport on May 19.
The former Army major was not present when his case was called at Edinburgh Sheriff Court yesterday.
Fiscal depute Calum Darling said: "I have here a letter from the accused in which he indicates that he is presently out of Scotland on a walking holiday and he indicates that he wishes to return and consult with his solicitor in person."
However, a statement on Joyce's website later said that was not the case. He added: "In fact, the fiscal depute clearly mixed up his paperwork and erroneously read out a month-old letter which related to a previous date, 7 August.
"Of course I made no such request in relation to today."
A spokesman for the Crown Office said: "We will look into the point that Mr Joyce has raised and deal with it before the case next calls in court."
Sheriff Alistair Noble continued the case without plea until September 26. Joyce is ordained to appear in court on that date.
Joyce is also charged with resisting constables Alan Hazelwood and John Miller at the airport and on the way to the city's St Leonard's police office. The MP, from Stirling, is said to have struggled violently and tried to kick the officers.
The independent Falkirk MP is stepping down from his role in 2015.
