I do not seem to be able to replicate that when I activate a colormap that I have set a specific size for.
cmap = flag(10);
colormap(cmap);
colorbar()

Use the 'tick' property to specify tick locations. See this related answer: https://www.mathworks.com/matlabcentral/answers/447758-how-place-the-tick-at-the-mid-value-of-specific-color-range-and-uniform-color-bar-across-different-r
% Create data & plot
data = peaks(25);
contourf(data)
cmap = jet(14);
colormap(cmap);
% Specify tick locations in colorbar automatically
cl = clim;
ct = linspace(cl(1),cl(2),size(cmap,1)+1);
c=colorbar('Ticks',ct);
