So Many Bugs – OfficeSuite docs & PDF editor Review

I am questioning why I am paying $30 a year subscription for a spreadsheet app that has so many bugs. Dates sometimes do not appear with correct year re: entering 06/14/1934 displays 06/14/1938, no matter how many times I enter it or remove all formatting then reformat. Also spreadsheet functions sometimes yield crazy results or as in =Count not counting just cells with numbers. Many other bugs all the time. Still better than Excel 365 which has limited functionality in iOS. Would rate 5stars if it worked ok.
