On February 10, 2017, DR Music announced that BP Rania would start promotions for their second song "Make Me Ah" from the ''Start a Fire'' EP, on February 14. It was also announced that this would be the first time that Alex would take part in the entire choreography. On February 21, DR Music revealed that they were approached by a "well established production company" with an acting opportunity for Alex, to which they responded by releasing a statement saying that they hoped that fans could understand the benefits of this opportunity, and that the opportunity would "allow the group to gain exposure and help BP Rania's success by expanding their fan base." DR Music assured the fans that Alex would remain a fully active member of BP Rania, and would return to her regular schedules after she returned to Korea. Around the same time INGENIOMedia announced that on February 28, they were opening preorders for BP Rania's first compilation album ''Rania Legends'', comprising songs from "Dr Feel Good" to "Start a Fire", with the requirement that 100 preorders be made before they began manufacturing the albums. As well, they stated that all money raised would be dedicated to the production of a mini documentary titled "20 Days With BP RaNia", with any leftover money invested in the production of BP RaNia's next release. The release was eventually cancelled and pre-orders refunded, but INGENIOmedia said that all songs would be re-recorded by BP RaNia and included as a bonus CD and DVD in their next release instead. On May 12, DR Music announced that they were looking for three to four new members to start BP Rania W, a worldwide group that would promote alongside the current members of BP Rania.

BP Rania continued as a six-member group, releasing their fifth EP ''Refresh 7th'' on August 12, with title track "Beep Beep Beep". Promotions became controversial when fans and viewers noticed that Alex had few lines and spent the majority of the performance standing to the side while the remaining five members continued to dance and sing. When fans asked the company to clarify, the choreographer responded "

said she won't do it because she's a rapper", to which Alex replied via Twitter "If these lies keep magically surfacing, I'll go ahead and come out with the truth. Let it really hit the fan." DR Music then issued a statement saying "The rumors that Alexandra was not willing, able, or present at practice to participate in the full choreography are false. Her level of talent is surpassed only by her work ethic and dedication to the team. It is for those reasons that we gave her the position of leader." Soon afterwards it was announced that Alex had left the group. On September 13, it was announced that the group would be making a comeback with "Breathe Heavy" from their ''Refresh 7th'' EP.
