Things got a little tense on Monday’s Dancing with the Stars.

“It needed more samba content in there. There was so much larking about,” judge Len Goodman said after Gleb Savchenko and Jana Kramer’s 1970s -set samaba they’d been assigned for Eras Week on the ABC reality dance competition. “You know it’s the truth, Gleb.”

Savchenko began listing the samba moves performed in the routine, to which Goodman responded, “I saw what you did. I know what you did … don’t get me started Gleb. You just listen to what I’m telling you and get on with it.”

Backstage, Savchenko told co-host Erin Andrews, “I think we have to mix it up a little because it’s not a dance competition, it’s a TV show.” But in the ballroom – unseen by the audience – Goodman told his fellow judges, “No. It’s a dance competition.”

Goodman ended up giving the couple an 8, but after the live show Savchenko still appeared heated about the interaction.

“I think Len should spend more time with us rather than in England,” he told PEOPLE, referring to Goodman’s absence from DWTS while he judged the British reality TV show Strictly Come Dancing.

The pro dancer did concede that Goodman had some worthwhile points, but maintained that his and Kramer’s “50/50” split between traditional samba and 1970s fun was the right balance to strike.

“When you’ve been given a special theme for a dance, you want to incorporate some of those moves,” he said. “You have to kind of let people see what it is. That’s why we have the costumes and wigs and everything.”

“There is a fine balance between a show number and just a samba,” he said. “No one wants to see a minute and forty seconds of just samba, especially when you’re dealing with someone who’s never danced before. Jana did an amazing job and I’m so proud of her. She killed it.”

Dancing with the Stars airs Mondays at 8 p.m. ET on ABC.
