Function defining in Calc

Hello. I use LibreOffice 4.1.3 in Kubuntu 13.10. In my case, function defining in Calc works very strange. There are only a few functions on default that work. Others will appear only if I have already used them. However, financial functions do not appear even after using them.
For example:
If I type «=S», «SUM()» will be offered. But if I type «=SI» first time, nothing is offered till I add «N(». However after first use, it becomes available with only «=SI». Moreover, «ACCRINT()» does not appear even after first use.
Can I fix it somehow?

Do a try resetting the user profile, sometimes solves strange issues.

Thank you, but it does not help.
