Problem with padding and lost of data

I am having two problems when I use libgcrypt:

1) When I use padding, it is not removed during the decryption. And I am
adding the "(flags pkcs1)" to S-expression before decrypt.

2) If I do not use padding and I encrypt and decrypt a block of bytes
which starts with the byte zero, I lose that first byte after decryption.

I attached a program that I am using to test libgcrypt.

Does anyone can help me?
