Rspec System Test passes when run individually, fails when run with entire suite

I have the following test that passes when I run it in isolation:

require 'rails_helper'
RSpec.describe ‘deleting a non-recurring user event’, js: true do
let(:user)       { create(:proofreader_user) }

let(:date)       { Date.current.strftime(‘%Y-%m-%d’) }

let(:date_time)  { date + ’ 00:00’}
it ‘deletes the event’ do

visit root_path

click_on “Login”

fill_in  “Email”,    with: user.email

fill_in  “Password”, with: user.password

click_on “Sign In”

visit calendar_path

expect(current_path).to eq(calendar_path)

expect(page).to have_css(“#complete_registration:disabled”)

expect(page).to_not have_css(“td.fc-event-container”)

find(“td.fc-day[data-date=‘#{date}’]”).click

expect(page).to have_css(“div#user-event-modal”)

expect(page).to have_select(‘user_event[title]’, :options => UserEvent.titles.keys)

expect(find(‘input’, id: ‘user_event_starting’).value).to eq date_time

expect(find(‘input’, id: ‘user_event_ending’).value).to eq date_time

page.execute_script(“$(‘input#user_event_starting’).val(‘#{date} 09:00’)”)

expect(find(‘input’, id: ‘user_event_starting’).value).to eq date + ’ 09:00’

page.execute_script(“$(‘input#user_event_ending’).val(‘#{date} 12:00’)”)

expect(find(‘input’, id: ‘user_event_ending’).value).to eq date + ’ 12:00’

click_on ‘Save’

expect(page).to have_css(“td.fc-event-container a.fc-day-grid-event”)

expect(page).to have_css(“span.fc-time”, text: ‘9a - 12p’)

expect(page).to have_css(“span.fc-title”, text: ‘work’)

find(“span.fc-time”, text: ‘9a - 12p’).click

expect(page).to have_css(“div#user-event-modal”)

find(“#del_one_event”).click

within(‘.swal2-actions’) { click_button(‘Yes’) }

wait_for { page }.to_not have_css(“div#user-event-modal”)

expect(page).to_not have_css(“td.fc-event-container”)

expect(page).to_not have_css(“span.fc-time”, text: ‘10a - 14p’)

end

end

However, when I run all of the tests I get the following error:

Failure/Error: within(‘.swal2-actions’) { click_button(‘Yes’) }

 Capybara::ElementNotFound:
   Unable to find visible css ".swal2-actions"

Why does this test fail when I run it with the other test and how can I fix it so it passes when I run all tests?
