Grace notes with easyHeadsOIn error

[Viktor Mastoridis]

Hello Lilypond users,

I hope that this is the right place to ask the following question:

Using Lilypond 2.18.2

I am using easyHeadsOn (with numbers: \Ez_numbers_engraver) on a score.

I tried to use \afterGrace or \grace, as in 

\afterGrace  b8  ( c16 )

but the result is that the number  and the head of the grace note are bigger than the rest of the heads/numbers (not smaller as expected).

I tried to use the property \small, 

\afterGrace  b8   ( \small c16 ) d8

but then the rest of the composition loses its even-grouping. 

If easyHeads is turned off, afterGrace notes behave as expected.

I attach images of the three situations.
