Not saving entries

Sorry just want to add, for some reason it will work but only if I type ‘test’ in the first and last name fields. if I put a real name in it wont save the entry.
After a couple test entries where added I tried the search function on the front page and the ‘test’ search results where now repeating x3 of the same result.
I only have x2 entries with first names being ‘test’ and ‘test1’
