How can I solve the orthogonality issue in bior3.5 wavelet?

Dear everyone,

I am trying to decompose a time series with the use of Biorthogonal Wavelet Pairs, but I receive an error ''Wavelet must be orthogonal''. The code I am using is the following

load DM_USD
wname='bior3.5'
boundary = 'reflection';
lev = 6;
whp = modwt( DM_USD, wname, lev, boundary );

I would appreciate any help. Thank you in advance.
