LibreOffice Calc mouse right-click menu does not show for all cells, suggests variants of the word (spell checker)

Inside Libre Office Calc when i mouse right-click some (not all of the cells) of same column, it does not trigger regular cell context menu, but opens menu which suggests fixes for the string, like if i spelled it wrong. But that is not the case, i am just using custom abbreviations/shortcuts for a company names, like lets say AMSC.

When I go to a Tools menu on the top, and disable spell checking, it starts working (showing regular context menu). But what if i do not want to disable spell check entirely?

The cell category is number, General format, english language, font/language is set to none.

Actually i am unable to again reproduce the issue, unable to find (or do not remember) which menu entry i have clicked in Tools menu (third item from the right. Rightmost is Help menu.).

By setting the text to None you have disabled spell check.
.
If, instead of right clicking on the cell, you left click and then press the Menu key on the keyboard, you will always get the context menu even if there is a spelling error flagged
