Strange autoreplace

Hi all:
I am using Libreoffice 6.2.4.2.0 on spanish.
I am having a trouble when i use the writer. Every time that i write (3) inside a text table, the three in parenthesis is replaced by 3.000. same for 1, 2. I really want disable FOR EVER in all any document that i write this malfunction correction.

Is really annoyning because is required press 5 keys to write 3.000, and is required 5 keys to write (3) (2 are shift) so are not any advantage. This function/bug have really no sense more than do difficult to the user.

Best Regards to all.

Please check your AutoCorrect Options at Tools -> AutoCorrect -> AutoCorrect Options -> Tab: Replace though I’ve got little hope, since I cannot reproduce the error when using spanish language - neither in Calc nor in Writer / Writer table (but I’m using 6.2.5.2).
