pet resue lost 300 levels but see stars of past levels

BKK

When I started pet rescue on android phone, I was on level 486 instead of about 786.  I see the stars from the past levels but no level numbers are visible.  I want to be able to return to this level. My name is Beverly on Pet rescue. Last  night I completed the 10th level of pet island.  The boosters appear to be unchanged.
