Galleries alignment problem

I am displaying the galleries within albums using this code
[album id=1 template=compact]

The problem I encounter is that the galleries don’t align properly
please see link below, they just mis-aligned randomly, and for some reason, it is aligned to the right instead of the left side.

I don’t think it is a theme problem since I’ve having this problem with everything I’ve used.

I appreciate any help.
Thank you in advance.
