Recently we have observed frequently changing the class IDs for fields in the list and list details block. We have built custom code features based on the classes; every 2 to 3 days, the IDs are changing. At least the field ID should be constant. ex: This is the list block field class id earlier .pk1erb1, but now ._7568359_pk1erb1 and it is changing every 2nd day, If the team is changing frequently, it is very difficult to build custom CSS and functions.
