LS,
Small capacitors are marked in several ways it may have the actual value
expressed as a decimal, such as 2.2 or there may be an "R" in place of
the decimal point, such as 2R2. It is all the same. How they are
marked depends on the manufacturer, and is subject to change from time
to time.
C33 can be 2 pF, 2.2 pF (also marked with 2R2 - same thing)
C22 can be 2.7 pF, 3 pF or 3.3 pF - the decimal point may be replaced
with an R in any of these.
It seems you have the correct capacitors located.
73,
