Where did you get this biorthogonal filter pair? It does not satisfy the criteria for a biorthogonal (wavelet) filter pair. For one example, the product of the Fourier transforms of the lowpass filters at 0 frequency (DC) should be equal to 2.
In your case, it is equal to -2. The sum of elements in your rlp filter is -2.
A couple things you need to ensure are the following, let G_0() and G_1() denote the Fourier transforms of your lowpass filters and H_0() and H_1() denote your highpass filters
G_0(\omega)G_1^*(\omega)+H_0(\omega)H_1^*(\omega) = 2
G_0(\omega)G_1^*(\omega+\pi)+H_0(\omega)H_1^*(\omega+\pi) = 0
where the * denotes the complex conjugate.
