Thanks Tony. You are right.

This is my first PEG grammar and I don't see this detail. Change the order in Primary nonterminal solve my problem.

The first alternative for Primary is TerminalString. This means that if
any other alternative starts with a TerminalString it cannot match, since
the Primary has already succeeded. For instance, a later alternative is
RepeatedSequence and many of its alternatives start with strings. Your
example should match a RepeatedSequence but cannot.
