Of the turacos formerly united in the genus Tauraco, the leucotis/ruspolii clade is now treated by WGAC as Menelikornis leucotis and Menelikornis ruspolii, and the porphyreolophus/johnstoni clade (of which the latter was formerly in Ruwenzorornis) as Gallirex porphyreolophus and Gallirex ruspolii, in concordance with the phylogeny of Perktaş et al. (2020). The continued treatment of the two species of Musophaga as a separate genus to the exclusion of T. macrorhyncha and T. verreauxi, however,does not agree with the Perktaş et al. (2020) tree, though it is intuitive on morphological grounds, and further study is required.

Unintended disagreements occur when a parent (B) is
thinned by swapping a child (E) to another part of the
taxonomic tree, resulting in existing IDs of the parent being interpreted
as disagreements with existing IDs of the swapped child.
Identification
ID 2 of taxon E will be an unintended disagreement with ID 1 of taxon B after the taxon swap
If thinning a parent results in more than 10 unintended disagreements, you
should split the parent after swapping the child to replace existing IDs
of the parent (B) with IDs that don't disagree.
