The confusion comes because there are two distinct ideas of Tent of Meeting.
Exodus 33:7 Young's Literal Translation
And Moses taketh the tent, and hath stretched it out at the outside of the camp, afar off from the camp, and hath called it, 'Tent of Meeting;' [Ohel Moed] and it hath come to pass, every one seeking Jehovah goeth out unto the tent of meeting, which is at the outside of the camp.
Call this one "Moses Tent of Meeting".
Exodus 40:24 Young's Literal Translation
And he putteth the candlestick in the tent of meeting [Ohel Moed], over-against the table, on the side of the tabernacle [Mishkan] southward,
Call this one "Priestly Tent of Meeting".
In Hebrew, both appears as אֹ֣הֶל מוֹעֵ֔ד (Ohel Moed) but they are quite different.
Moses Tent of Meeting is placed outside of the camp while the Priestly Tent of Meeting is surrounded by the 12 tribes.
'>Each by his standard, with ensigns of the house of their fathers, do the sons of Israel encamp; over-against round about the tent of meeting they encamp.'
And it hath come to pass, at the going in of Moses to the tent, the pillar of the cloud cometh down, and hath stood at the opening of the tent, and He hath spoken with Moses;
The pillar of the cloud comes and goes at Moses Tent of Meeting but it stays at the Priestly Tent of Meeting.
Exodus 40:34 And the cloud covereth the tent of meeting, and the honour of Jehovah hath filled the tabernacle; 35and Moses hath not been able to go in unto the tent of meeting, for the cloud hath tabernacled on it, and the honour of Jehovah hath filled the tabernacle. 36And in the going up of the cloud from off the tabernacle the sons of Israel journey in all their journeys; 37and if the cloud go not up then they journey not, until the day of its going up: 38for the cloud of Jehovah [is] on the tabernacle by day, and fire is in it by night, before the eyes of all the house of Israel in all their journeys.
Moses Tent of Meeting was a temporary shelter until the Priestly Tent of Meeting had been constructed.
Strictly speaking, the Tabernacle includes the Priestly Tent of Meeting and the court space containing the bronze altar. Further confusion comes when Tabernacle and Tent of Meeting are used interchangeably on occasions.
And the charge of the sons of Gershon in the tent of meeting [is] the tabernacle, and the tent, its covering, and the vail at the opening of the tent of meeting, 26and the hangings of the court, and the vail at the opening of the court, which [is] by the tabernacle and by the altar round about, and its cords, to all its service.
