In Yaaleh v'yavo (p. 57) zachreinu...bo,[1] ufakdeinu vo[2]

Compiled and arranged by the Lubavitcher Rebbe, Rabbi Menachem Mendel Schneerson, of righteous memory, in 5703 (1943) from the talks and letters of the sixth Chabad Rebbe, Rabbi Yosef Yitzchak Schneersohn, of righteous memory.

The word bo spelled with the letter beit - i.e., with a dagesh point.

The same word spelled here vo, with the letter veit - i.e., without the dagesh point.

ביעלה ויבוא: זכרנו ה"א [ה' אלוקינו] בו - בית דגושה - ופקדנו בו - בית רפוי'.
