PWA list isn't load text correctly ( only in IOS phone )

i recently use pwa ionic for my project, but i found some problem in ios phone.

first problem is, my ion-list text is not load correctly
There are 6 data in the array,
and it’s already show 6 row, but text only showed in 1 top row, the last 5 row not showing the text in the array.

second is, there are 5 tabs in my app, and the first problem is in tab number 4
when i build for the first time, i still could click tab number 4, and it will redirect to another page, but when i build again, when i click tab number 4, it won’t redirect to anywhere,
i don’t change the code, just rebuild it

is there any solution for this problem,
thank you
