German discount retailer Lidl, which opened its first U.S. stores in 2017, is scaling back its U.S. ambitions.

Lidl had hoped to open 100 stores by Summer 2018 — the one-year anniversary of its first U.S. opening — but it’s now on track to have just 67 opened by the end of 2018, according to a story in the German business magazine Manager Magazin.

Klaus Gehrig, head of the Neckarsulm Schwarz group, Lidl’s parent company, told the magazine that Lidl expects to open just 20 U.S. stores this year. The company opened 47 in 2017.  

Miscalculations were made in the selection of some markets and regarding store sizes, according to the story.
