Rule parser accept wrong syntax and generate buggy automaton

The rule below is wrong. Either there should be parentheses around `t_capital_1st` or the `{1-3}` should be moved out of the group:
`@Street::,? (de la|de|du|des|à|aux)? ($NC|$NP|t_capital_1st{1-3}):LOCATION:`

But the parser silently accepts it and produces an automaton which matches wrongly and produces a corrupted analyses graph. When analyzing `Cette maison est la plus belle de la rue.`, "rue" is wrongly matched and replaced by a token with no linguistic data (see graph below)
