Apparent wrong answer: synonyms ending with letter e to word "bad"

I asked ChatGPT-3.5 (actually GPT-4 had similar errors):
give me a list of synonyms ending with letter e to word bad

and I got:
Here are some synonyms of the word “bad” that end with the letter “e”:

  • abominable
  • deplorable
  • intolerable
  • insufferable
  • miserable
  • unsatisfactory
  • unpalatable
  • inadequate
  • wretched
  • hopeless
  • unsound
  • flawed

I then said:
please check the condition “ending with letter e”

and I got:
I apologize for the mistake in my previous response. To clarify, there are no synonyms of the word “bad” that end with the letter “e”.

Are these kind of errors expected for ChatGPT?
