Formidable form is making recurrent update queries

Hi Formidable team, I am using this plugin on my site and it is incredible, but for a few days, my site is responding very slow, once enquiring issue on Query Monitor, I find that it is creating the same update queries (36 in nos) regularly. Query is as follows:
UPDATEwp_options`
SET option_value = ‘a:3:{s:7:\”review2\”;a:11:{s:7:\”message\”;s:214:\”If you are enjoying Formidable, could you do me a BIG favor and give us a review to help me grow my little business and boost our motivation?<br/>- Steph Wells<br/><span>Co-Founder and CTO of Formidable Forms<span>\”;s:7:\”subject\”;s:57:\”Congratulations!
