You account was on free plan back in September and for free users total submission storage is 500 submissions. Most likely because of that your submissions were removed from your account.
I have now restored your submissions. Now you have 8956 submissions on your account and you have unlimited submissions storage. You can check this on usage page of your account.
Hope this will help. Let us know if you need further assistance.
