comment (Very) ill-behaved Piecewise Plot
and for the first problem, try Plot[Interp2[s, {1, 1}, {2, 3}, {3, 3}, {4, 4}, {5, 5}, {6, 3}] // Evaluate, {s, 1, 6}, PlotRange -> Full, Exclusions -> None]

comment LogLikelihood function with Multivariate State Space Models
could you make a simpler version of your question? It seems unlikely that the problem arises because of 10 dimensions?

or FunctionalD[ Integrate[ K[z - Subscript[x, 1]] f[Subscript[x, 1]], {Subscript[x, 1], -Infinity, Infinity}], f[y]] … a pity :-)

comment Can we teach Mathematica about functional differentiation?
FYI your generic definition fails on FunctionalD[G[f[x]^], f[y]].
